Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617368, here are decompositions:

7 + 31617361 = 31617368
439 + 31616929 = 31617368
619 + 31616749 = 31617368
661 + 31616707 = 31617368
691 + 31616677 = 31617368
829 + 31616539 = 31617368
859 + 31616509 = 31617368
967 + 31616401 = 31617368

Showing the first eight; more decompositions exist.
