Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594456, here are decompositions:

83 + 31594373 = 31594456
263 + 31594193 = 31594456
293 + 31594163 = 31594456
359 + 31594097 = 31594456
503 + 31593953 = 31594456
587 + 31593869 = 31594456
617 + 31593839 = 31594456
659 + 31593797 = 31594456

Showing the first eight; more decompositions exist.
