Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594810, here are decompositions:

3 + 31594807 = 31594810
11 + 31594799 = 31594810
41 + 31594769 = 31594810
53 + 31594757 = 31594810
83 + 31594727 = 31594810
197 + 31594613 = 31594810
227 + 31594583 = 31594810
257 + 31594553 = 31594810

Showing the first eight; more decompositions exist.
