Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 984870, here are decompositions:

11 + 984859 = 984870
17 + 984853 = 984870
23 + 984847 = 984870
53 + 984817 = 984870
109 + 984761 = 984870
113 + 984757 = 984870
137 + 984733 = 984870
163 + 984707 = 984870

Showing the first eight; more decompositions exist.
