Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597588, here are decompositions:

17 + 31597571 = 31597588
47 + 31597541 = 31597588
251 + 31597337 = 31597588
389 + 31597199 = 31597588
461 + 31597127 = 31597588
467 + 31597121 = 31597588
557 + 31597031 = 31597588
839 + 31596749 = 31597588

Showing the first eight; more decompositions exist.
