Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607576, here are decompositions:

73 + 31607503 = 31607576
103 + 31607473 = 31607576
127 + 31607449 = 31607576
277 + 31607299 = 31607576
283 + 31607293 = 31607576
313 + 31607263 = 31607576
349 + 31607227 = 31607576
439 + 31607137 = 31607576

Showing the first eight; more decompositions exist.
