Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595822, here are decompositions:

103 + 31595719 = 31595822
151 + 31595671 = 31595822
211 + 31595611 = 31595822
229 + 31595593 = 31595822
241 + 31595581 = 31595822
439 + 31595383 = 31595822
571 + 31595251 = 31595822
613 + 31595209 = 31595822

Showing the first eight; more decompositions exist.
