Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961638, here are decompositions:

5 + 961633 = 961638
11 + 961627 = 961638
19 + 961619 = 961638
37 + 961601 = 961638
71 + 961567 = 961638
89 + 961549 = 961638
107 + 961531 = 961638
109 + 961529 = 961638

Showing the first eight; more decompositions exist.
