Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597366, here are decompositions:

29 + 31597337 = 31597366
83 + 31597283 = 31597366
113 + 31597253 = 31597366
167 + 31597199 = 31597366
239 + 31597127 = 31597366
389 + 31596977 = 31597366
443 + 31596923 = 31597366
467 + 31596899 = 31597366

Showing the first eight; more decompositions exist.
