Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616276, here are decompositions:

19 + 31616257 = 31616276
103 + 31616173 = 31616276
127 + 31616149 = 31616276
163 + 31616113 = 31616276
229 + 31616047 = 31616276
277 + 31615999 = 31616276
283 + 31615993 = 31616276
547 + 31615729 = 31616276

Showing the first eight; more decompositions exist.
