Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009218, here are decompositions:

11 + 1009207 = 1009218
17 + 1009201 = 1009218
19 + 1009199 = 1009218
29 + 1009189 = 1009218
59 + 1009159 = 1009218
61 + 1009157 = 1009218
79 + 1009139 = 1009218
97 + 1009121 = 1009218

Showing the first eight; more decompositions exist.
