Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961786, here are decompositions:

3 + 961783 = 961786
17 + 961769 = 961786
29 + 961757 = 961786
47 + 961739 = 961786
53 + 961733 = 961786
83 + 961703 = 961786
107 + 961679 = 961786
149 + 961637 = 961786

Showing the first eight; more decompositions exist.
