Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595934, here are decompositions:

5 + 31595929 = 31595934
53 + 31595881 = 31595934
61 + 31595873 = 31595934
67 + 31595867 = 31595934
101 + 31595833 = 31595934
103 + 31595831 = 31595934
127 + 31595807 = 31595934
151 + 31595783 = 31595934

Showing the first eight; more decompositions exist.
