Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499956, here are decompositions:

17 + 31499939 = 31499956
23 + 31499933 = 31499956
113 + 31499843 = 31499956
419 + 31499537 = 31499956
557 + 31499399 = 31499956
569 + 31499387 = 31499956
647 + 31499309 = 31499956
659 + 31499297 = 31499956

Showing the first eight; more decompositions exist.
