Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597368, here are decompositions:

31 + 31597337 = 31597368
107 + 31597261 = 31597368
137 + 31597231 = 31597368
191 + 31597177 = 31597368
239 + 31597129 = 31597368
241 + 31597127 = 31597368
269 + 31597099 = 31597368
317 + 31597051 = 31597368

Showing the first eight; more decompositions exist.
