Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595916, here are decompositions:

43 + 31595873 = 31595916
47 + 31595869 = 31595916
83 + 31595833 = 31595916
109 + 31595807 = 31595916
139 + 31595777 = 31595916
193 + 31595723 = 31595916
197 + 31595719 = 31595916
199 + 31595717 = 31595916

Showing the first eight; more decompositions exist.
