Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616124, here are decompositions:

11 + 31616113 = 31616124
83 + 31616041 = 31616124
101 + 31616023 = 31616124
103 + 31616021 = 31616124
107 + 31616017 = 31616124
131 + 31615993 = 31616124
151 + 31615973 = 31616124
173 + 31615951 = 31616124

Showing the first eight; more decompositions exist.
