Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594312, here are decompositions:

3 + 31594309 = 31594312
41 + 31594271 = 31594312
149 + 31594163 = 31594312
179 + 31594133 = 31594312
251 + 31594061 = 31594312
263 + 31594049 = 31594312
353 + 31593959 = 31594312
359 + 31593953 = 31594312

Showing the first eight; more decompositions exist.
