Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016820, here are decompositions:

31 + 1016789 = 1016820
37 + 1016783 = 1016820
43 + 1016777 = 1016820
47 + 1016773 = 1016820
71 + 1016749 = 1016820
83 + 1016737 = 1016820
89 + 1016731 = 1016820
131 + 1016689 = 1016820

Showing the first eight; more decompositions exist.
