Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595122, here are decompositions:

59 + 31595063 = 31595122
101 + 31595021 = 31595122
113 + 31595009 = 31595122
131 + 31594991 = 31595122
191 + 31594931 = 31595122
239 + 31594883 = 31595122
311 + 31594811 = 31595122
353 + 31594769 = 31595122

Showing the first eight; more decompositions exist.
