Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595770, here are decompositions:

47 + 31595723 = 31595770
53 + 31595717 = 31595770
83 + 31595687 = 31595770
113 + 31595657 = 31595770
197 + 31595573 = 31595770
383 + 31595387 = 31595770
491 + 31595279 = 31595770
593 + 31595177 = 31595770

Showing the first eight; more decompositions exist.
