Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595794, here are decompositions:

11 + 31595783 = 31595794
17 + 31595777 = 31595794
23 + 31595771 = 31595794
71 + 31595723 = 31595794
107 + 31595687 = 31595794
137 + 31595657 = 31595794
227 + 31595567 = 31595794
311 + 31595483 = 31595794

Showing the first eight; more decompositions exist.
