Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577708, here are decompositions:

61 + 31577647 = 31577708
181 + 31577527 = 31577708
199 + 31577509 = 31577708
307 + 31577401 = 31577708
439 + 31577269 = 31577708
499 + 31577209 = 31577708
577 + 31577131 = 31577708
691 + 31577017 = 31577708

Showing the first eight; more decompositions exist.
