Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595874, here are decompositions:

5 + 31595869 = 31595874
7 + 31595867 = 31595874
41 + 31595833 = 31595874
43 + 31595831 = 31595874
67 + 31595807 = 31595874
97 + 31595777 = 31595874
103 + 31595771 = 31595874
151 + 31595723 = 31595874

Showing the first eight; more decompositions exist.
