	Goldbach's conjecture - Wikipedia, the free encyclopedia
		In mathematics, Goldbach's conjecture is one of the oldest unsolved problems in number theory and in all of mathematics.
		The strong Goldbach conjecture is in fact very similar to the twin prime conjecture, and the two conjectures are believed to be of roughly comparable difficulty.
		Because it is easily understood by laymen, Goldbach's conjecture is a popular target for pseudomathematicians who attempt to prove it, sometimes even disprove it, using only high-school-level mathematics.

	Goldbachs formodning - Wikipedia
		Goldbachs formodning er et av de eldste uløste problemene i matematikk.
		Goldbach fremsatte i sitt brev til Euler formodningen at ethvert oddetall større enn 5 kan skrives som summen av tre primtall.
		I sitt svar foreslo Euler formodningen som i dag er kjent som Goldbachs formodning, også kalt Goldbachs sterke formodning.

	Introduction to Arithmetic: Number Theory; Prime Numbers, Fermat Theorem, Goldbach Conjecture and Diophantine Equations (Site not responding. Last check: 2007-11-05)
		One of the most famous problems in number theory is Goldbach's conjecture, proposed in 1742 by Christian Goldbach (1690-1764), the Prussian-born number theorist and analyst, in a letter to Leonhard Euler.
		Goldbach's conjecture states that any even number greater than or equal to 6 can be expressed as the sum of two odd prime numbers (for example, 6 = 3 + 3, 8 = 5 + 3, 48 = 29 + 19).
		Goldbach's conjecture is a good example of the way in which a problem in number theory can be stated very simply yet be very difficult to solve.

	Goldbach conjecture
		In its original form, now known as the weak Goldbach conjecture, it was put forward by the Prussian amateur mathematician and historian Christian Goldbach (1690-1764) in a letter dated Jun. 7, 1742, to Leonhard Euler.
		In this guise it says that every whole number greater than 5 is the sum of three prime numbers.
		Euler restated this, in an equivalent form, as what is now called the strong Goldbach conjecture or, simply, the Goldbach conjecture: every even number greater than 2 is the sum of two primes.

		Goldbach's Conjecture (GC) was first stated in 1742, in a letter written by the minor mathematician Christian Goldbach (tutor to the Czar's children) to the great Swiss mathematician Leonard Euler.
		Goldbach, in his letter, pointed out to Euler his observation that "every whole number greater than six seems to be the sum of three primes".
		Today, the former is known by mathematicians as "Goldbach's Conjecture" while the latter is known as "the second", the "other" or the "weaker" GC.

	GOLDBACH'S CONJECTURE
		The great novel "Uncle Petros and Goldbach's conjecture" published by Faber and Faber, UK, earnestly takes us through the absorptions of a mathematician of dedicated spirit like that of Uncle Petros who having devoted whole of his life and till the last breath to capture demonstrable proof of it, though no such demonstrable proof followed.
		The present volume is titled as "Goldbach Theorem" as the truth of the conjecture stands established.
		Those whose anxiety naturally would be first of all to go to the Proof itself, they may straight-a-way go to the last pages of Chapter-1, and then to revert back to the beginning of Chapter-1 to have parallel movement with the evolutionary emergence of the elementary approach culminating into the Proof.

		In 1742, historian and mathematician Christian Goldbach (1690–1764) wrote a letter to Leonhard Euler (1707–1783) in which he suggested, in effect, that every integer greater than 5 is the sum of three prime numbers.
		The Goldbach conjecture is then equivalent to the statement that the number of Goldbach partitions is greater than 0.
		In plotting the relative frequency of occurrence of a prime, p, in the minimal Goldbach partition of the even numbers, you can observe that there is a distinct difference in behavior when p is of the form 3k + 1 and when it is not.
