Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017218, here are decompositions:

19 + 1017199 = 1017218
61 + 1017157 = 1017218
79 + 1017139 = 1017218
157 + 1017061 = 1017218
211 + 1017007 = 1017218
271 + 1016947 = 1017218
277 + 1016941 = 1017218
337 + 1016881 = 1017218

Showing the first eight; more decompositions exist.
