Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028588, here are decompositions:

7 + 1028581 = 1028588
19 + 1028569 = 1028588
31 + 1028557 = 1028588
79 + 1028509 = 1028588
109 + 1028479 = 1028588
151 + 1028437 = 1028588
199 + 1028389 = 1028588
271 + 1028317 = 1028588

Showing the first eight; more decompositions exist.
