Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596566, here are decompositions:

13 + 31596553 = 31596566
163 + 31596403 = 31596566
373 + 31596193 = 31596566
439 + 31596127 = 31596566
499 + 31596067 = 31596566
577 + 31595989 = 31596566
733 + 31595833 = 31596566
997 + 31595569 = 31596566

Showing the first eight; more decompositions exist.
