Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961662, here are decompositions:

5 + 961657 = 961662
19 + 961643 = 961662
29 + 961633 = 961662
43 + 961619 = 961662
61 + 961601 = 961662
113 + 961549 = 961662
131 + 961531 = 961662
151 + 961511 = 961662

Showing the first eight; more decompositions exist.
