Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617848, here are decompositions:

37 + 31617811 = 31617848
151 + 31617697 = 31617848
181 + 31617667 = 31617848
439 + 31617409 = 31617848
487 + 31617361 = 31617848
919 + 31616929 = 31617848
991 + 31616857 = 31617848
1009 + 31616839 = 31617848

Showing the first eight; more decompositions exist.
