Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565676, here are decompositions:

5 + 31565671 = 31565676
13 + 31565663 = 31565676
73 + 31565603 = 31565676
137 + 31565539 = 31565676
179 + 31565497 = 31565676
239 + 31565437 = 31565676
277 + 31565399 = 31565676
293 + 31565383 = 31565676

Showing the first eight; more decompositions exist.
