Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961808, here are decompositions:

19 + 961789 = 961808
31 + 961777 = 961808
61 + 961747 = 961808
79 + 961729 = 961808
151 + 961657 = 961808
181 + 961627 = 961808
241 + 961567 = 961808
277 + 961531 = 961808

Showing the first eight; more decompositions exist.
