Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597108, here are decompositions:

131 + 31596977 = 31597108
227 + 31596881 = 31597108
251 + 31596857 = 31597108
269 + 31596839 = 31597108
311 + 31596797 = 31597108
359 + 31596749 = 31597108
401 + 31596707 = 31597108
797 + 31596311 = 31597108

Showing the first eight; more decompositions exist.
