Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595702, here are decompositions:

31 + 31595671 = 31595702
109 + 31595593 = 31595702
331 + 31595371 = 31595702
601 + 31595101 = 31595702
643 + 31595059 = 31595702
739 + 31594963 = 31595702
829 + 31594873 = 31595702
1021 + 31594681 = 31595702

Showing the first eight; more decompositions exist.
