Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595170, here are decompositions:

29 + 31595141 = 31595170
107 + 31595063 = 31595170
149 + 31595021 = 31595170
179 + 31594991 = 31595170
239 + 31594931 = 31595170
251 + 31594919 = 31595170
263 + 31594907 = 31595170
293 + 31594877 = 31595170

Showing the first eight; more decompositions exist.
