Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565484, here are decompositions:

11 + 31565473 = 31565484
23 + 31565461 = 31565484
47 + 31565437 = 31565484
53 + 31565431 = 31565484
61 + 31565423 = 31565484
73 + 31565411 = 31565484
101 + 31565383 = 31565484
107 + 31565377 = 31565484

Showing the first eight; more decompositions exist.
