Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961650, here are decompositions:

7 + 961643 = 961650
13 + 961637 = 961650
17 + 961633 = 961650
23 + 961627 = 961650
31 + 961619 = 961650
37 + 961613 = 961650
83 + 961567 = 961650
101 + 961549 = 961650

Showing the first eight; more decompositions exist.
