Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597594, here are decompositions:

23 + 31597571 = 31597594
53 + 31597541 = 31597594
101 + 31597493 = 31597594
227 + 31597367 = 31597594
257 + 31597337 = 31597594
311 + 31597283 = 31597594
443 + 31597151 = 31597594
467 + 31597127 = 31597594

Showing the first eight; more decompositions exist.
