Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595206, here are decompositions:

17 + 31595189 = 31595206
29 + 31595177 = 31595206
197 + 31595009 = 31595206
449 + 31594757 = 31595206
479 + 31594727 = 31595206
593 + 31594613 = 31595206
653 + 31594553 = 31595206
659 + 31594547 = 31595206

Showing the first eight; more decompositions exist.
