Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961806, here are decompositions:

17 + 961789 = 961806
23 + 961783 = 961806
29 + 961777 = 961806
37 + 961769 = 961806
59 + 961747 = 961806
67 + 961739 = 961806
73 + 961733 = 961806
103 + 961703 = 961806

Showing the first eight; more decompositions exist.
