Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610986, here are decompositions:

257 + 31610729 = 31610986
263 + 31610723 = 31610986
347 + 31610639 = 31610986
467 + 31610519 = 31610986
593 + 31610393 = 31610986
647 + 31610339 = 31610986
653 + 31610333 = 31610986
773 + 31610213 = 31610986

Showing the first eight; more decompositions exist.
