Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597716, here are decompositions:

19 + 31597697 = 31597716
23 + 31597693 = 31597716
43 + 31597673 = 31597716
103 + 31597613 = 31597716
113 + 31597603 = 31597716
167 + 31597549 = 31597716
223 + 31597493 = 31597716
233 + 31597483 = 31597716

Showing the first eight; more decompositions exist.
