Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600564, here are decompositions:

41 + 31600523 = 31600564
53 + 31600511 = 31600564
71 + 31600493 = 31600564
113 + 31600451 = 31600564
257 + 31600307 = 31600564
263 + 31600301 = 31600564
431 + 31600133 = 31600564
461 + 31600103 = 31600564

Showing the first eight; more decompositions exist.
