Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528480, here are decompositions:

11 + 528469 = 528480
47 + 528433 = 528480
61 + 528419 = 528480
67 + 528413 = 528480
79 + 528401 = 528480
89 + 528391 = 528480
97 + 528383 = 528480
107 + 528373 = 528480

Showing the first eight; more decompositions exist.
