Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594794, here are decompositions:

37 + 31594757 = 31594794
47 + 31594747 = 31594794
67 + 31594727 = 31594794
103 + 31594691 = 31594794
113 + 31594681 = 31594794
167 + 31594627 = 31594794
181 + 31594613 = 31594794
197 + 31594597 = 31594794

Showing the first eight; more decompositions exist.
