Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 984778, here are decompositions:

17 + 984761 = 984778
29 + 984749 = 984778
71 + 984707 = 984778
89 + 984689 = 984778
167 + 984611 = 984778
191 + 984587 = 984778
239 + 984539 = 984778
281 + 984497 = 984778

Showing the first eight; more decompositions exist.
