Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985820, here are decompositions:

13 + 985807 = 985820
37 + 985783 = 985820
61 + 985759 = 985820
79 + 985741 = 985820
97 + 985723 = 985820
163 + 985657 = 985820
181 + 985639 = 985820
223 + 985597 = 985820

Showing the first eight; more decompositions exist.
