Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594746, here are decompositions:

17 + 31594729 = 31594746
19 + 31594727 = 31594746
47 + 31594699 = 31594746
137 + 31594609 = 31594746
149 + 31594597 = 31594746
163 + 31594583 = 31594746
167 + 31594579 = 31594746
173 + 31594573 = 31594746

Showing the first eight; more decompositions exist.
