Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595846, here are decompositions:

13 + 31595833 = 31595846
127 + 31595719 = 31595846
193 + 31595653 = 31595846
277 + 31595569 = 31595846
379 + 31595467 = 31595846
439 + 31595407 = 31595846
463 + 31595383 = 31595846
673 + 31595173 = 31595846

Showing the first eight; more decompositions exist.
