Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597176, here are decompositions:

47 + 31597129 = 31597176
173 + 31597003 = 31597176
179 + 31596997 = 31597176
199 + 31596977 = 31597176
227 + 31596949 = 31597176
263 + 31596913 = 31597176
269 + 31596907 = 31597176
277 + 31596899 = 31597176

Showing the first eight; more decompositions exist.
