Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597494, here are decompositions:

11 + 31597483 = 31597494
23 + 31597471 = 31597494
41 + 31597453 = 31597494
83 + 31597411 = 31597494
127 + 31597367 = 31597494
157 + 31597337 = 31597494
211 + 31597283 = 31597494
233 + 31597261 = 31597494

Showing the first eight; more decompositions exist.
