Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596858, here are decompositions:

11 + 31596847 = 31596858
19 + 31596839 = 31596858
37 + 31596821 = 31596858
61 + 31596797 = 31596858
89 + 31596769 = 31596858
101 + 31596757 = 31596858
107 + 31596751 = 31596858
109 + 31596749 = 31596858

Showing the first eight; more decompositions exist.
