Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020480, here are decompositions:

23 + 1020457 = 1020480
29 + 1020451 = 1020480
61 + 1020419 = 1020480
67 + 1020413 = 1020480
73 + 1020407 = 1020480
79 + 1020401 = 1020480
101 + 1020379 = 1020480
127 + 1020353 = 1020480

Showing the first eight; more decompositions exist.
