Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594318, here are decompositions:

47 + 31594271 = 31594318
71 + 31594247 = 31594318
167 + 31594151 = 31594318
257 + 31594061 = 31594318
269 + 31594049 = 31594318
359 + 31593959 = 31594318
449 + 31593869 = 31594318
479 + 31593839 = 31594318

Showing the first eight; more decompositions exist.
