Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566534, here are decompositions:

7 + 31566527 = 31566534
11 + 31566523 = 31566534
17 + 31566517 = 31566534
37 + 31566497 = 31566534
47 + 31566487 = 31566534
53 + 31566481 = 31566534
61 + 31566473 = 31566534
107 + 31566427 = 31566534

Showing the first eight; more decompositions exist.
