Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028608, here are decompositions:

11 + 1028597 = 1028608
29 + 1028579 = 1028608
47 + 1028561 = 1028608
137 + 1028471 = 1028608
197 + 1028411 = 1028608
281 + 1028327 = 1028608
401 + 1028207 = 1028608
419 + 1028189 = 1028608

Showing the first eight; more decompositions exist.
