Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597512, here are decompositions:

5 + 31597507 = 31597512
19 + 31597493 = 31597512
29 + 31597483 = 31597512
41 + 31597471 = 31597512
59 + 31597453 = 31597512
101 + 31597411 = 31597512
229 + 31597283 = 31597512
251 + 31597261 = 31597512

Showing the first eight; more decompositions exist.
