Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961824, here are decompositions:

7 + 961817 = 961824
11 + 961813 = 961824
13 + 961811 = 961824
41 + 961783 = 961824
47 + 961777 = 961824
67 + 961757 = 961824
137 + 961687 = 961824
163 + 961661 = 961824

Showing the first eight; more decompositions exist.
