Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594186, here are decompositions:

23 + 31594163 = 31594186
53 + 31594133 = 31594186
89 + 31594097 = 31594186
137 + 31594049 = 31594186
227 + 31593959 = 31594186
233 + 31593953 = 31594186
317 + 31593869 = 31594186
347 + 31593839 = 31594186

Showing the first eight; more decompositions exist.
