Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961858, here are decompositions:

5 + 961853 = 961858
11 + 961847 = 961858
17 + 961841 = 961858
41 + 961817 = 961858
47 + 961811 = 961858
89 + 961769 = 961858
101 + 961757 = 961858
167 + 961691 = 961858

Showing the first eight; more decompositions exist.
