Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596720, here are decompositions:

7 + 31596713 = 31596720
11 + 31596709 = 31596720
13 + 31596707 = 31596720
41 + 31596679 = 31596720
47 + 31596673 = 31596720
59 + 31596661 = 31596720
83 + 31596637 = 31596720
107 + 31596613 = 31596720

Showing the first eight; more decompositions exist.
