Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028490, here are decompositions:

11 + 1028479 = 1028490
17 + 1028473 = 1028490
19 + 1028471 = 1028490
53 + 1028437 = 1028490
79 + 1028411 = 1028490
97 + 1028393 = 1028490
101 + 1028389 = 1028490
157 + 1028333 = 1028490

Showing the first eight; more decompositions exist.
