Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028670, here are decompositions:

7 + 1028663 = 1028670
23 + 1028647 = 1028670
53 + 1028617 = 1028670
73 + 1028597 = 1028670
89 + 1028581 = 1028670
101 + 1028569 = 1028670
109 + 1028561 = 1028670
113 + 1028557 = 1028670

Showing the first eight; more decompositions exist.
