Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594540, here are decompositions:

167 + 31594373 = 31594540
269 + 31594271 = 31594540
293 + 31594247 = 31594540
347 + 31594193 = 31594540
389 + 31594151 = 31594540
443 + 31594097 = 31594540
479 + 31594061 = 31594540
491 + 31594049 = 31594540

Showing the first eight; more decompositions exist.
