Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595032, here are decompositions:

11 + 31595021 = 31595032
23 + 31595009 = 31595032
41 + 31594991 = 31595032
71 + 31594961 = 31595032
101 + 31594931 = 31595032
113 + 31594919 = 31595032
149 + 31594883 = 31595032
233 + 31594799 = 31595032

Showing the first eight; more decompositions exist.
