Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576704, here are decompositions:

23 + 31576681 = 31576704
31 + 31576673 = 31576704
163 + 31576541 = 31576704
193 + 31576511 = 31576704
227 + 31576477 = 31576704
251 + 31576453 = 31576704
277 + 31576427 = 31576704
293 + 31576411 = 31576704

Showing the first eight; more decompositions exist.
