Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595894, here are decompositions:

13 + 31595881 = 31595894
61 + 31595833 = 31595894
163 + 31595731 = 31595894
193 + 31595701 = 31595894
223 + 31595671 = 31595894
241 + 31595653 = 31595894
283 + 31595611 = 31595894
313 + 31595581 = 31595894

Showing the first eight; more decompositions exist.
