Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985818, here are decompositions:

11 + 985807 = 985818
19 + 985799 = 985818
37 + 985781 = 985818
59 + 985759 = 985818
89 + 985729 = 985818
109 + 985709 = 985818
139 + 985679 = 985818
151 + 985667 = 985818

Showing the first eight; more decompositions exist.
