Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596866, here are decompositions:

19 + 31596847 = 31596866
73 + 31596793 = 31596866
97 + 31596769 = 31596866
109 + 31596757 = 31596866
157 + 31596709 = 31596866
193 + 31596673 = 31596866
229 + 31596637 = 31596866
283 + 31596583 = 31596866

Showing the first eight; more decompositions exist.
