Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595836, here are decompositions:

3 + 31595833 = 31595836
5 + 31595831 = 31595836
29 + 31595807 = 31595836
53 + 31595783 = 31595836
59 + 31595777 = 31595836
113 + 31595723 = 31595836
149 + 31595687 = 31595836
179 + 31595657 = 31595836

Showing the first eight; more decompositions exist.
