Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 984820, here are decompositions:

3 + 984817 = 984820
59 + 984761 = 984820
71 + 984749 = 984820
113 + 984707 = 984820
131 + 984689 = 984820
227 + 984593 = 984820
233 + 984587 = 984820
257 + 984563 = 984820

Showing the first eight; more decompositions exist.
