Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468570, here are decompositions:

11 + 31468559 = 31468570
17 + 31468553 = 31468570
41 + 31468529 = 31468570
47 + 31468523 = 31468570
53 + 31468517 = 31468570
59 + 31468511 = 31468570
71 + 31468499 = 31468570
167 + 31468403 = 31468570

Showing the first eight; more decompositions exist.
