Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595910, here are decompositions:

29 + 31595881 = 31595910
37 + 31595873 = 31595910
41 + 31595869 = 31595910
43 + 31595867 = 31595910
79 + 31595831 = 31595910
103 + 31595807 = 31595910
127 + 31595783 = 31595910
139 + 31595771 = 31595910

Showing the first eight; more decompositions exist.
