Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961816, here are decompositions:

3 + 961813 = 961816
5 + 961811 = 961816
47 + 961769 = 961816
59 + 961757 = 961816
83 + 961733 = 961816
113 + 961703 = 961816
137 + 961679 = 961816
173 + 961643 = 961816

Showing the first eight; more decompositions exist.
