Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568036, here are decompositions:

37 + 31567999 = 31568036
223 + 31567813 = 31568036
307 + 31567729 = 31568036
337 + 31567699 = 31568036
349 + 31567687 = 31568036
433 + 31567603 = 31568036
523 + 31567513 = 31568036
607 + 31567429 = 31568036

Showing the first eight; more decompositions exist.
