Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616118, here are decompositions:

5 + 31616113 = 31616118
59 + 31616059 = 31616118
71 + 31616047 = 31616118
97 + 31616021 = 31616118
101 + 31616017 = 31616118
109 + 31616009 = 31616118
139 + 31615979 = 31616118
167 + 31615951 = 31616118

Showing the first eight; more decompositions exist.
