Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016988, here are decompositions:

17 + 1016971 = 1016988
29 + 1016959 = 1016988
41 + 1016947 = 1016988
47 + 1016941 = 1016988
59 + 1016929 = 1016988
61 + 1016927 = 1016988
67 + 1016921 = 1016988
79 + 1016909 = 1016988

Showing the first eight; more decompositions exist.
