Goldbach's conjecture

Chen, a prodigious talent, spent a lifetime working on Goldbach’s conjecture — the still unsolved theory that every even integer greater than two is the sum of two prime numbers.

In making the closing argument for the motion of no confidence during Wednesday’s debate, Tom Watson, the deputy leader of the Labour Party, was careful to acknowledge the efforts that May had already made to solve the political equivalent of Goldbach’s conjecture.

For instance, we now know that Goldbach’s conjecture holds up to 4 x 1018.

One of the most famous unsolved problems involving primes is Goldbach’s conjecture, which states that every even number greater than 2 can be expressed as the sum of two primes.

Goldbach’s conjecture, which states that every even integer is the sum of two primes, is known to be true for numbers up to 1018.
