Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961646, here are decompositions:

3 + 961643 = 961646
13 + 961633 = 961646
19 + 961627 = 961646
79 + 961567 = 961646
97 + 961549 = 961646
139 + 961507 = 961646
193 + 961453 = 961646
199 + 961447 = 961646

Showing the first eight; more decompositions exist.
