Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028660, here are decompositions:

13 + 1028647 = 1028660
43 + 1028617 = 1028660
79 + 1028581 = 1028660
103 + 1028557 = 1028660
151 + 1028509 = 1028660
181 + 1028479 = 1028660
223 + 1028437 = 1028660
271 + 1028389 = 1028660

Showing the first eight; more decompositions exist.
