Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596690, here are decompositions:

11 + 31596679 = 31596690
17 + 31596673 = 31596690
19 + 31596671 = 31596690
29 + 31596661 = 31596690
53 + 31596637 = 31596690
79 + 31596611 = 31596690
107 + 31596583 = 31596690
137 + 31596553 = 31596690

Showing the first eight; more decompositions exist.
