Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596960, here are decompositions:

11 + 31596949 = 31596960
37 + 31596923 = 31596960
47 + 31596913 = 31596960
53 + 31596907 = 31596960
61 + 31596899 = 31596960
71 + 31596889 = 31596960
79 + 31596881 = 31596960
103 + 31596857 = 31596960

Showing the first eight; more decompositions exist.
