Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600560, here are decompositions:

11 + 31600549 = 31600560
29 + 31600531 = 31600560
31 + 31600529 = 31600560
37 + 31600523 = 31600560
67 + 31600493 = 31600560
107 + 31600453 = 31600560
109 + 31600451 = 31600560
113 + 31600447 = 31600560

Showing the first eight; more decompositions exist.
