Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 984872, here are decompositions:

13 + 984859 = 984872
19 + 984853 = 984872
139 + 984733 = 984872
331 + 984541 = 984872
523 + 984349 = 984872
571 + 984301 = 984872
619 + 984253 = 984872
631 + 984241 = 984872

Showing the first eight; more decompositions exist.
