Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463646, here are decompositions:

59 + 31463587 = 31463646
113 + 31463533 = 31463646
127 + 31463519 = 31463646
139 + 31463507 = 31463646
157 + 31463489 = 31463646
163 + 31463483 = 31463646
239 + 31463407 = 31463646
257 + 31463389 = 31463646

Showing the first eight; more decompositions exist.
