Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556768, here are decompositions:

31 + 31556737 = 31556768
211 + 31556557 = 31556768
307 + 31556461 = 31556768
379 + 31556389 = 31556768
619 + 31556149 = 31556768
757 + 31556011 = 31556768
769 + 31555999 = 31556768
787 + 31555981 = 31556768

Showing the first eight; more decompositions exist.
