Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594066, here are decompositions:

3 + 31594063 = 31594066
5 + 31594061 = 31594066
17 + 31594049 = 31594066
83 + 31593983 = 31594066
107 + 31593959 = 31594066
113 + 31593953 = 31594066
197 + 31593869 = 31594066
227 + 31593839 = 31594066

Showing the first eight; more decompositions exist.
