Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468566, here are decompositions:

7 + 31468559 = 31468566
13 + 31468553 = 31468566
23 + 31468543 = 31468566
37 + 31468529 = 31468566
43 + 31468523 = 31468566
67 + 31468499 = 31468566
113 + 31468453 = 31468566
163 + 31468403 = 31468566

Showing the first eight; more decompositions exist.
