Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597416, here are decompositions:

5 + 31597411 = 31597416
79 + 31597337 = 31597416
163 + 31597253 = 31597416
173 + 31597243 = 31597416
239 + 31597177 = 31597416
317 + 31597099 = 31597416
373 + 31597043 = 31597416
419 + 31596997 = 31597416

Showing the first eight; more decompositions exist.
