Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565714, here are decompositions:

13 + 31565701 = 31565714
43 + 31565671 = 31565714
223 + 31565491 = 31565714
241 + 31565473 = 31565714
277 + 31565437 = 31565714
283 + 31565431 = 31565714
331 + 31565383 = 31565714
337 + 31565377 = 31565714

Showing the first eight; more decompositions exist.
