Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594288, here are decompositions:

17 + 31594271 = 31594288
41 + 31594247 = 31594288
137 + 31594151 = 31594288
191 + 31594097 = 31594288
227 + 31594061 = 31594288
239 + 31594049 = 31594288
419 + 31593869 = 31594288
449 + 31593839 = 31594288

Showing the first eight; more decompositions exist.
