Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616216, here are decompositions:

43 + 31616173 = 31616216
67 + 31616149 = 31616216
103 + 31616113 = 31616216
157 + 31616059 = 31616216
193 + 31616023 = 31616216
199 + 31616017 = 31616216
223 + 31615993 = 31616216
367 + 31615849 = 31616216

Showing the first eight; more decompositions exist.
