Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571846, here are decompositions:

13 + 31571833 = 31571846
37 + 31571809 = 31571846
43 + 31571803 = 31571846
67 + 31571779 = 31571846
139 + 31571707 = 31571846
193 + 31571653 = 31571846
199 + 31571647 = 31571846
277 + 31571569 = 31571846

Showing the first eight; more decompositions exist.
