Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595738, here are decompositions:

7 + 31595731 = 31595738
19 + 31595719 = 31595738
37 + 31595701 = 31595738
67 + 31595671 = 31595738
127 + 31595611 = 31595738
157 + 31595581 = 31595738
271 + 31595467 = 31595738
331 + 31595407 = 31595738

Showing the first eight; more decompositions exist.
