Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616504, here are decompositions:

103 + 31616401 = 31616504
223 + 31616281 = 31616504
331 + 31616173 = 31616504
457 + 31616047 = 31616504
463 + 31616041 = 31616504
487 + 31616017 = 31616504
613 + 31615891 = 31616504
853 + 31615651 = 31616504

Showing the first eight; more decompositions exist.
