Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595158, here are decompositions:

17 + 31595141 = 31595158
137 + 31595021 = 31595158
149 + 31595009 = 31595158
167 + 31594991 = 31595158
197 + 31594961 = 31595158
227 + 31594931 = 31595158
239 + 31594919 = 31595158
251 + 31594907 = 31595158

Showing the first eight; more decompositions exist.
