Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595852, here are decompositions:

19 + 31595833 = 31595852
151 + 31595701 = 31595852
181 + 31595671 = 31595852
199 + 31595653 = 31595852
241 + 31595611 = 31595852
271 + 31595581 = 31595852
283 + 31595569 = 31595852
601 + 31595251 = 31595852

Showing the first eight; more decompositions exist.
