Goldbach's conjecture is a prominent unsolved problem in number theory that dates back to 1742. It was proposed by the Prussian mathematician Christian Goldbach in a letter to Leonhard Euler, a leading mathematician of the time. The conjecture can be stated in two forms: the strong form and the weak form, both concerning the sums of prime numbers.

This is the original form as stated by Goldbach. It proposes that every even integer greater than 2 can be expressed as the sum of two prime numbers. For example,

4 = 2 + 2,
6 = 3 + 3,
8 = 3 + 5,

and so on.

Despite the seeming simplicity of the statement, Goldbach's conjecture has been neither proved nor disproved and remains one of the oldest unsolved questions in mathematics. It has been tested extensively by mathematicians and computer scientists for large numbers, and so far, no counterexamples have been found, lending numerical support to the conjecture. However, in the realm of mathematics, empirical evidence is not sufficient; a formal proof is necessary to establish the truth of the statement.

Various efforts have been made to tackle this conjecture or to prove weaker versions of it. For instance, the weak form of Goldbach's conjecture was proven for sufficiently large numbers by Vinogradov in the 1930s, and later the threshold was lowered significantly by other mathematicians. However, the full conjecture, especially the strong form, remains open. The pursuit of a proof or disproof of Goldbach's conjecture continues to be a significant and intriguing challenge in the field of number theory.
