Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028658, here are decompositions:

11 + 1028647 = 1028658
41 + 1028617 = 1028658
61 + 1028597 = 1028658
79 + 1028579 = 1028658
89 + 1028569 = 1028658
97 + 1028561 = 1028658
101 + 1028557 = 1028658
149 + 1028509 = 1028658

Showing the first eight; more decompositions exist.
