Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597764, here are decompositions:

43 + 31597721 = 31597764
47 + 31597717 = 31597764
67 + 31597697 = 31597764
71 + 31597693 = 31597764
113 + 31597651 = 31597764
151 + 31597613 = 31597764
193 + 31597571 = 31597764
223 + 31597541 = 31597764

Showing the first eight; more decompositions exist.
