Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961664, here are decompositions:

3 + 961661 = 961664
7 + 961657 = 961664
31 + 961633 = 961664
37 + 961627 = 961664
97 + 961567 = 961664
157 + 961507 = 961664
211 + 961453 = 961664
271 + 961393 = 961664

Showing the first eight; more decompositions exist.
