Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961668, here are decompositions:

5 + 961663 = 961668
7 + 961661 = 961668
11 + 961657 = 961668
31 + 961637 = 961668
41 + 961627 = 961668
67 + 961601 = 961668
101 + 961567 = 961668
137 + 961531 = 961668

Showing the first eight; more decompositions exist.
