Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595182, here are decompositions:

5 + 31595177 = 31595182
41 + 31595141 = 31595182
173 + 31595009 = 31595182
191 + 31594991 = 31595182
251 + 31594931 = 31595182
263 + 31594919 = 31595182
383 + 31594799 = 31595182
491 + 31594691 = 31595182

Showing the first eight; more decompositions exist.
