Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595146, here are decompositions:

5 + 31595141 = 31595146
83 + 31595063 = 31595146
137 + 31595009 = 31595146
227 + 31594919 = 31595146
239 + 31594907 = 31595146
263 + 31594883 = 31595146
269 + 31594877 = 31595146
347 + 31594799 = 31595146

Showing the first eight; more decompositions exist.
