Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617118, here are decompositions:

17 + 31617101 = 31617118
41 + 31617077 = 31617118
89 + 31617029 = 31617118
107 + 31617011 = 31617118
131 + 31616987 = 31617118
167 + 31616951 = 31617118
227 + 31616891 = 31617118
389 + 31616729 = 31617118

Showing the first eight; more decompositions exist.
