Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594826, here are decompositions:

13 + 31594813 = 31594826
19 + 31594807 = 31594826
79 + 31594747 = 31594826
97 + 31594729 = 31594826
127 + 31594699 = 31594826
199 + 31594627 = 31594826
229 + 31594597 = 31594826
337 + 31594489 = 31594826

Showing the first eight; more decompositions exist.
