Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597756, here are decompositions:

17 + 31597739 = 31597756
59 + 31597697 = 31597756
83 + 31597673 = 31597756
263 + 31597493 = 31597756
389 + 31597367 = 31597756
419 + 31597337 = 31597756
503 + 31597253 = 31597756
557 + 31597199 = 31597756

Showing the first eight; more decompositions exist.
