Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051518, here are decompositions:

11 + 1051507 = 1051518
19 + 1051499 = 1051518
37 + 1051481 = 1051518
47 + 1051471 = 1051518
59 + 1051459 = 1051518
101 + 1051417 = 1051518
109 + 1051409 = 1051518
199 + 1051319 = 1051518

Showing the first eight; more decompositions exist.
