Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508544, here are decompositions:

17 + 31508527 = 31508544
37 + 31508507 = 31508544
83 + 31508461 = 31508544
101 + 31508443 = 31508544
127 + 31508417 = 31508544
181 + 31508363 = 31508544
233 + 31508311 = 31508544
257 + 31508287 = 31508544

Showing the first eight; more decompositions exist.
