Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607936, here are decompositions:

67 + 31607869 = 31607936
79 + 31607857 = 31607936
97 + 31607839 = 31607936
307 + 31607629 = 31607936
337 + 31607599 = 31607936
433 + 31607503 = 31607936
463 + 31607473 = 31607936
487 + 31607449 = 31607936

Showing the first eight; more decompositions exist.
