Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 984780, here are decompositions:

19 + 984761 = 984780
23 + 984757 = 984780
31 + 984749 = 984780
47 + 984733 = 984780
73 + 984707 = 984780
79 + 984701 = 984780
113 + 984667 = 984780
163 + 984617 = 984780

Showing the first eight; more decompositions exist.
