Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597514, here are decompositions:

7 + 31597507 = 31597514
31 + 31597483 = 31597514
43 + 31597471 = 31597514
61 + 31597453 = 31597514
97 + 31597417 = 31597514
103 + 31597411 = 31597514
271 + 31597243 = 31597514
283 + 31597231 = 31597514

Showing the first eight; more decompositions exist.
