Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594146, here are decompositions:

13 + 31594133 = 31594146
83 + 31594063 = 31594146
97 + 31594049 = 31594146
107 + 31594039 = 31594146
163 + 31593983 = 31594146
193 + 31593953 = 31594146
277 + 31593869 = 31594146
307 + 31593839 = 31594146

Showing the first eight; more decompositions exist.
