Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016778, here are decompositions:

5 + 1016773 = 1016778
29 + 1016749 = 1016778
41 + 1016737 = 1016778
47 + 1016731 = 1016778
89 + 1016689 = 1016778
97 + 1016681 = 1016778
137 + 1016641 = 1016778
157 + 1016621 = 1016778

Showing the first eight; more decompositions exist.
