Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616264, here are decompositions:

3 + 31616261 = 31616264
7 + 31616257 = 31616264
13 + 31616251 = 31616264
151 + 31616113 = 31616264
223 + 31616041 = 31616264
241 + 31616023 = 31616264
271 + 31615993 = 31616264
313 + 31615951 = 31616264

Showing the first eight; more decompositions exist.
