Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609514, here are decompositions:

61 + 31609453 = 31609514
283 + 31609231 = 31609514
397 + 31609117 = 31609514
421 + 31609093 = 31609514
577 + 31608937 = 31609514
631 + 31608883 = 31609514
661 + 31608853 = 31609514
691 + 31608823 = 31609514

Showing the first eight; more decompositions exist.
