Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 984640, here are decompositions:

23 + 984617 = 984640
29 + 984611 = 984640
47 + 984593 = 984640
53 + 984587 = 984640
101 + 984539 = 984640
149 + 984491 = 984640
179 + 984461 = 984640
227 + 984413 = 984640

Showing the first eight; more decompositions exist.
