Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463628, here are decompositions:

37 + 31463591 = 31463628
41 + 31463587 = 31463628
101 + 31463527 = 31463628
109 + 31463519 = 31463628
139 + 31463489 = 31463628
151 + 31463477 = 31463628
199 + 31463429 = 31463628
239 + 31463389 = 31463628

Showing the first eight; more decompositions exist.
