Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607984, here are decompositions:

13 + 31607971 = 31607984
127 + 31607857 = 31607984
193 + 31607791 = 31607984
313 + 31607671 = 31607984
433 + 31607551 = 31607984
523 + 31607461 = 31607984
643 + 31607341 = 31607984
691 + 31607293 = 31607984

Showing the first eight; more decompositions exist.
