Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595066, here are decompositions:

3 + 31595063 = 31595066
7 + 31595059 = 31595066
67 + 31594999 = 31595066
79 + 31594987 = 31595066
103 + 31594963 = 31595066
163 + 31594903 = 31595066
193 + 31594873 = 31595066
199 + 31594867 = 31595066

Showing the first eight; more decompositions exist.
