Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028528, here are decompositions:

19 + 1028509 = 1028528
139 + 1028389 = 1028528
199 + 1028329 = 1028528
211 + 1028317 = 1028528
307 + 1028221 = 1028528
337 + 1028191 = 1028528
379 + 1028149 = 1028528
421 + 1028107 = 1028528

Showing the first eight; more decompositions exist.
