Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595012, here are decompositions:

3 + 31595009 = 31595012
13 + 31594999 = 31595012
109 + 31594903 = 31595012
139 + 31594873 = 31595012
151 + 31594861 = 31595012
199 + 31594813 = 31595012
283 + 31594729 = 31595012
313 + 31594699 = 31595012

Showing the first eight; more decompositions exist.
