Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616514, here are decompositions:

5 + 31616509 = 31616514
103 + 31616411 = 31616514
113 + 31616401 = 31616514
151 + 31616363 = 31616514
227 + 31616287 = 31616514
233 + 31616281 = 31616514
257 + 31616257 = 31616514
263 + 31616251 = 31616514

Showing the first eight; more decompositions exist.
