Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616510, here are decompositions:

31 + 31616479 = 31616510
109 + 31616401 = 31616510
151 + 31616359 = 31616510
223 + 31616287 = 31616510
229 + 31616281 = 31616510
337 + 31616173 = 31616510
397 + 31616113 = 31616510
463 + 31616047 = 31616510

Showing the first eight; more decompositions exist.
