Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616294, here are decompositions:

7 + 31616287 = 31616294
13 + 31616281 = 31616294
37 + 31616257 = 31616294
43 + 31616251 = 31616294
181 + 31616113 = 31616294
271 + 31616023 = 31616294
277 + 31616017 = 31616294
373 + 31615921 = 31616294

Showing the first eight; more decompositions exist.
