Polignac's conjecture

In number theory, Polignac's conjecture was made by Alphonse de Polignac in 1849 and states:

For any positive even number n, there are infinitely many prime gaps of size n. In other words: There are infinitely many cases of two consecutive prime numbers with difference n.^[1]

The conjecture has not yet been proven or disproven for a given value of n. In 2013 an important breakthrough was made by Zhang Yitang who proved that there are infinitely many prime gaps of size n for some value of n < 70,000,000.

• n=2,就是孪素数猜想,张之后,我想会有比70000000更小的数被证明.但n=2,maybe impossible. -jinjing- ♀ (0 bytes) () 05/26/2013 postreply 16:37:33
