Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594806, here are decompositions:

7 + 31594799 = 31594806
37 + 31594769 = 31594806
59 + 31594747 = 31594806
79 + 31594727 = 31594806
107 + 31594699 = 31594806
179 + 31594627 = 31594806
193 + 31594613 = 31594806
197 + 31594609 = 31594806

Showing the first eight; more decompositions exist.
