Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607036, here are decompositions:

73 + 31606963 = 31607036
79 + 31606957 = 31607036
157 + 31606879 = 31607036
283 + 31606753 = 31607036
379 + 31606657 = 31607036
457 + 31606579 = 31607036
499 + 31606537 = 31607036
607 + 31606429 = 31607036

Showing the first eight; more decompositions exist.
