Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617308, here are decompositions:

109 + 31617199 = 31617308
127 + 31617181 = 31617308
379 + 31616929 = 31617308
421 + 31616887 = 31617308
601 + 31616707 = 31617308
631 + 31616677 = 31617308
661 + 31616647 = 31617308
739 + 31616569 = 31617308

Showing the first eight; more decompositions exist.
