Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 984878, here are decompositions:

19 + 984859 = 984878
31 + 984847 = 984878
61 + 984817 = 984878
211 + 984667 = 984878
337 + 984541 = 984878
397 + 984481 = 984878
421 + 984457 = 984878
457 + 984421 = 984878

Showing the first eight; more decompositions exist.
