Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616174, here are decompositions:

61 + 31616113 = 31616174
127 + 31616047 = 31616174
151 + 31616023 = 31616174
157 + 31616017 = 31616174
181 + 31615993 = 31616174
223 + 31615951 = 31616174
283 + 31615891 = 31616174
367 + 31615807 = 31616174

Showing the first eight; more decompositions exist.
