Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597696, here are decompositions:

3 + 31597693 = 31597696
23 + 31597673 = 31597696
83 + 31597613 = 31597696
359 + 31597337 = 31597696
443 + 31597253 = 31597696
569 + 31597127 = 31597696
653 + 31597043 = 31597696
719 + 31596977 = 31597696

Showing the first eight; more decompositions exist.
