Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961666, here are decompositions:

3 + 961663 = 961666
5 + 961661 = 961666
23 + 961643 = 961666
29 + 961637 = 961666
47 + 961619 = 961666
53 + 961613 = 961666
137 + 961529 = 961666
179 + 961487 = 961666

Showing the first eight; more decompositions exist.
