Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595838, here are decompositions:

5 + 31595833 = 31595838
7 + 31595831 = 31595838
31 + 31595807 = 31595838
61 + 31595777 = 31595838
67 + 31595771 = 31595838
107 + 31595731 = 31595838
137 + 31595701 = 31595838
151 + 31595687 = 31595838

Showing the first eight; more decompositions exist.
