Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594386, here are decompositions:

13 + 31594373 = 31594386
53 + 31594333 = 31594386
113 + 31594273 = 31594386
139 + 31594247 = 31594386
149 + 31594237 = 31594386
193 + 31594193 = 31594386
223 + 31594163 = 31594386
227 + 31594159 = 31594386

Showing the first eight; more decompositions exist.
