Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595634, here are decompositions:

23 + 31595611 = 31595634
41 + 31595593 = 31595634
53 + 31595581 = 31595634
61 + 31595573 = 31595634
67 + 31595567 = 31595634
151 + 31595483 = 31595634
167 + 31595467 = 31595634
227 + 31595407 = 31595634

Showing the first eight; more decompositions exist.
