Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597354, here are decompositions:

17 + 31597337 = 31597354
71 + 31597283 = 31597354
101 + 31597253 = 31597354
227 + 31597127 = 31597354
233 + 31597121 = 31597354
311 + 31597043 = 31597354
431 + 31596923 = 31597354
557 + 31596797 = 31597354

Showing the first eight; more decompositions exist.
