Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566596, here are decompositions:

7 + 31566589 = 31566596
37 + 31566559 = 31566596
73 + 31566523 = 31566596
79 + 31566517 = 31566596
109 + 31566487 = 31566596
199 + 31566397 = 31566596
307 + 31566289 = 31566596
349 + 31566247 = 31566596

Showing the first eight; more decompositions exist.
