Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616310, here are decompositions:

13 + 31616297 = 31616310
23 + 31616287 = 31616310
29 + 31616281 = 31616310
53 + 31616257 = 31616310
59 + 31616251 = 31616310
79 + 31616231 = 31616310
127 + 31616183 = 31616310
137 + 31616173 = 31616310

Showing the first eight; more decompositions exist.
