Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607924, here are decompositions:

3 + 31607921 = 31607924
67 + 31607857 = 31607924
241 + 31607683 = 31607924
373 + 31607551 = 31607924
421 + 31607503 = 31607924
463 + 31607461 = 31607924
631 + 31607293 = 31607924
643 + 31607281 = 31607924

Showing the first eight; more decompositions exist.
