Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594906, here are decompositions:

3 + 31594903 = 31594906
23 + 31594883 = 31594906
29 + 31594877 = 31594906
107 + 31594799 = 31594906
137 + 31594769 = 31594906
149 + 31594757 = 31594906
179 + 31594727 = 31594906
293 + 31594613 = 31594906

Showing the first eight; more decompositions exist.
