Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961686, here are decompositions:

7 + 961679 = 961686
23 + 961663 = 961686
29 + 961657 = 961686
43 + 961643 = 961686
53 + 961633 = 961686
59 + 961627 = 961686
67 + 961619 = 961686
73 + 961613 = 961686

Showing the first eight; more decompositions exist.
