Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594498, here are decompositions:

167 + 31594331 = 31594498
227 + 31594271 = 31594498
251 + 31594247 = 31594498
347 + 31594151 = 31594498
401 + 31594097 = 31594498
449 + 31594049 = 31594498
659 + 31593839 = 31594498
701 + 31593797 = 31594498

Showing the first eight; more decompositions exist.
