Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597396, here are decompositions:

29 + 31597367 = 31597396
59 + 31597337 = 31597396
113 + 31597283 = 31597396
197 + 31597199 = 31597396
269 + 31597127 = 31597396
353 + 31597043 = 31597396
419 + 31596977 = 31597396
557 + 31596839 = 31597396

Showing the first eight; more decompositions exist.
