Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989864, here are decompositions:

37 + 989827 = 989864
61 + 989803 = 989864
67 + 989797 = 989864
103 + 989761 = 989864
193 + 989671 = 989864
223 + 989641 = 989864
241 + 989623 = 989864
283 + 989581 = 989864

Showing the first eight; more decompositions exist.
