Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961656, here are decompositions:

13 + 961643 = 961656
19 + 961637 = 961656
23 + 961633 = 961656
29 + 961627 = 961656
37 + 961619 = 961656
43 + 961613 = 961656
89 + 961567 = 961656
107 + 961549 = 961656

Showing the first eight; more decompositions exist.
