Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597536, here are decompositions:

29 + 31597507 = 31597536
43 + 31597493 = 31597536
53 + 31597483 = 31597536
83 + 31597453 = 31597536
199 + 31597337 = 31597536
283 + 31597253 = 31597536
293 + 31597243 = 31597536
337 + 31597199 = 31597536

Showing the first eight; more decompositions exist.
