Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597996, here are decompositions:

83 + 31597913 = 31597996
173 + 31597823 = 31597996
233 + 31597763 = 31597996
257 + 31597739 = 31597996
383 + 31597613 = 31597996
503 + 31597493 = 31597996
659 + 31597337 = 31597996
743 + 31597253 = 31597996

Showing the first eight; more decompositions exist.
