Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576768, here are decompositions:

17 + 31576751 = 31576768
29 + 31576739 = 31576768
59 + 31576709 = 31576768
149 + 31576619 = 31576768
227 + 31576541 = 31576768
239 + 31576529 = 31576768
257 + 31576511 = 31576768
359 + 31576409 = 31576768

Showing the first eight; more decompositions exist.
