Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016780, here are decompositions:

3 + 1016777 = 1016780
7 + 1016773 = 1016780
31 + 1016749 = 1016780
43 + 1016737 = 1016780
139 + 1016641 = 1016780
181 + 1016599 = 1016780
199 + 1016581 = 1016780
211 + 1016569 = 1016780

Showing the first eight; more decompositions exist.
