Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595022, here are decompositions:

13 + 31595009 = 31595022
23 + 31594999 = 31595022
31 + 31594991 = 31595022
59 + 31594963 = 31595022
61 + 31594961 = 31595022
103 + 31594919 = 31595022
139 + 31594883 = 31595022
149 + 31594873 = 31595022

Showing the first eight; more decompositions exist.
