Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961886, here are decompositions:

7 + 961879 = 961886
73 + 961813 = 961886
97 + 961789 = 961886
103 + 961783 = 961886
109 + 961777 = 961886
139 + 961747 = 961886
157 + 961729 = 961886
199 + 961687 = 961886

Showing the first eight; more decompositions exist.
