Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508596, here are decompositions:

17 + 31508579 = 31508596
29 + 31508567 = 31508596
47 + 31508549 = 31508596
89 + 31508507 = 31508596
179 + 31508417 = 31508596
233 + 31508363 = 31508596
419 + 31508177 = 31508596
443 + 31508153 = 31508596

Showing the first eight; more decompositions exist.
