Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600736, here are decompositions:

3 + 31600733 = 31600736
19 + 31600717 = 31600736
43 + 31600693 = 31600736
67 + 31600669 = 31600736
73 + 31600663 = 31600736
283 + 31600453 = 31600736
313 + 31600423 = 31600736
379 + 31600357 = 31600736

Showing the first eight; more decompositions exist.
