Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607852, here are decompositions:

13 + 31607839 = 31607852
61 + 31607791 = 31607852
163 + 31607689 = 31607852
181 + 31607671 = 31607852
223 + 31607629 = 31607852
271 + 31607581 = 31607852
349 + 31607503 = 31607852
379 + 31607473 = 31607852

Showing the first eight; more decompositions exist.
