Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015518, here are decompositions:

11 + 1015507 = 1015518
17 + 1015501 = 1015518
19 + 1015499 = 1015518
37 + 1015481 = 1015518
47 + 1015471 = 1015518
59 + 1015459 = 1015518
67 + 1015451 = 1015518
109 + 1015409 = 1015518

Showing the first eight; more decompositions exist.
