Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595944, here are decompositions:

71 + 31595873 = 31595944
113 + 31595831 = 31595944
137 + 31595807 = 31595944
167 + 31595777 = 31595944
173 + 31595771 = 31595944
227 + 31595717 = 31595944
257 + 31595687 = 31595944
461 + 31595483 = 31595944

Showing the first eight; more decompositions exist.
