Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496812, here are decompositions:

3 + 31496809 = 31496812
29 + 31496783 = 31496812
71 + 31496741 = 31496812
239 + 31496573 = 31496812
293 + 31496519 = 31496812
383 + 31496429 = 31496812
443 + 31496369 = 31496812
491 + 31496321 = 31496812

Showing the first eight; more decompositions exist.
