Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016978, here are decompositions:

7 + 1016971 = 1016978
19 + 1016959 = 1016978
31 + 1016947 = 1016978
37 + 1016941 = 1016978
97 + 1016881 = 1016978
139 + 1016839 = 1016978
229 + 1016749 = 1016978
241 + 1016737 = 1016978

Showing the first eight; more decompositions exist.
