Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616336, here are decompositions:

79 + 31616257 = 31616336
163 + 31616173 = 31616336
223 + 31616113 = 31616336
277 + 31616059 = 31616336
313 + 31616023 = 31616336
337 + 31615999 = 31616336
487 + 31615849 = 31616336
607 + 31615729 = 31616336

Showing the first eight; more decompositions exist.
