Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005456, here are decompositions:

17 + 1005439 = 1005456
19 + 1005437 = 1005456
29 + 1005427 = 1005456
43 + 1005413 = 1005456
47 + 1005409 = 1005456
83 + 1005373 = 1005456
97 + 1005359 = 1005456
107 + 1005349 = 1005456

Showing the first eight; more decompositions exist.
