Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028768, here are decompositions:

7 + 1028761 = 1028768
19 + 1028749 = 1028768
31 + 1028737 = 1028768
151 + 1028617 = 1028768
199 + 1028569 = 1028768
211 + 1028557 = 1028768
331 + 1028437 = 1028768
379 + 1028389 = 1028768

Showing the first eight; more decompositions exist.
