Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961866, here are decompositions:

5 + 961861 = 961866
13 + 961853 = 961866
19 + 961847 = 961866
53 + 961813 = 961866
83 + 961783 = 961866
89 + 961777 = 961866
97 + 961769 = 961866
109 + 961757 = 961866

Showing the first eight; more decompositions exist.
