Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597796, here are decompositions:

3 + 31597793 = 31597796
19 + 31597777 = 31597796
67 + 31597729 = 31597796
79 + 31597717 = 31597796
103 + 31597693 = 31597796
157 + 31597639 = 31597796
193 + 31597603 = 31597796
313 + 31597483 = 31597796

Showing the first eight; more decompositions exist.
