Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597576, here are decompositions:

5 + 31597571 = 31597576
83 + 31597493 = 31597576
239 + 31597337 = 31597576
293 + 31597283 = 31597576
449 + 31597127 = 31597576
599 + 31596977 = 31597576
653 + 31596923 = 31597576
677 + 31596899 = 31597576

Showing the first eight; more decompositions exist.
