Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597736, here are decompositions:

7 + 31597729 = 31597736
19 + 31597717 = 31597736
43 + 31597693 = 31597736
97 + 31597639 = 31597736
229 + 31597507 = 31597736
283 + 31597453 = 31597736
523 + 31597213 = 31597736
607 + 31597129 = 31597736

Showing the first eight; more decompositions exist.
