Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594786, here are decompositions:

17 + 31594769 = 31594786
29 + 31594757 = 31594786
59 + 31594727 = 31594786
173 + 31594613 = 31594786
233 + 31594553 = 31594786
239 + 31594547 = 31594786
593 + 31594193 = 31594786
653 + 31594133 = 31594786

Showing the first eight; more decompositions exist.
