Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028568, here are decompositions:

7 + 1028561 = 1028568
11 + 1028557 = 1028568
59 + 1028509 = 1028568
89 + 1028479 = 1028568
97 + 1028471 = 1028568
131 + 1028437 = 1028568
157 + 1028411 = 1028568
179 + 1028389 = 1028568

Showing the first eight; more decompositions exist.
