Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594678, here are decompositions:

131 + 31594547 = 31594678
257 + 31594421 = 31594678
347 + 31594331 = 31594678
431 + 31594247 = 31594678
617 + 31594061 = 31594678
719 + 31593959 = 31594678
809 + 31593869 = 31594678
839 + 31593839 = 31594678

Showing the first eight; more decompositions exist.
