Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594408, here are decompositions:

137 + 31594271 = 31594408
257 + 31594151 = 31594408
311 + 31594097 = 31594408
347 + 31594061 = 31594408
359 + 31594049 = 31594408
449 + 31593959 = 31594408
569 + 31593839 = 31594408
641 + 31593767 = 31594408

Showing the first eight; more decompositions exist.
