Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595824, here are decompositions:

17 + 31595807 = 31595824
41 + 31595783 = 31595824
47 + 31595777 = 31595824
53 + 31595771 = 31595824
101 + 31595723 = 31595824
107 + 31595717 = 31595824
137 + 31595687 = 31595824
167 + 31595657 = 31595824

Showing the first eight; more decompositions exist.
