Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595082, here are decompositions:

19 + 31595063 = 31595082
23 + 31595059 = 31595082
61 + 31595021 = 31595082
73 + 31595009 = 31595082
83 + 31594999 = 31595082
151 + 31594931 = 31595082
163 + 31594919 = 31595082
179 + 31594903 = 31595082

Showing the first eight; more decompositions exist.
