Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595038, here are decompositions:

17 + 31595021 = 31595038
29 + 31595009 = 31595038
47 + 31594991 = 31595038
107 + 31594931 = 31595038
131 + 31594907 = 31595038
227 + 31594811 = 31595038
239 + 31594799 = 31595038
269 + 31594769 = 31595038

Showing the first eight; more decompositions exist.
