Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594156, here are decompositions:

5 + 31594151 = 31594156
23 + 31594133 = 31594156
59 + 31594097 = 31594156
107 + 31594049 = 31594156
173 + 31593983 = 31594156
197 + 31593959 = 31594156
317 + 31593839 = 31594156
359 + 31593797 = 31594156

Showing the first eight; more decompositions exist.
