Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508614, here are decompositions:

47 + 31508567 = 31508614
107 + 31508507 = 31508614
197 + 31508417 = 31508614
251 + 31508363 = 31508614
383 + 31508231 = 31508614
443 + 31508171 = 31508614
461 + 31508153 = 31508614
521 + 31508093 = 31508614

Showing the first eight; more decompositions exist.
