Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028512, here are decompositions:

3 + 1028509 = 1028512
41 + 1028471 = 1028512
101 + 1028411 = 1028512
179 + 1028333 = 1028512
239 + 1028273 = 1028512
269 + 1028243 = 1028512
281 + 1028231 = 1028512
311 + 1028201 = 1028512

Showing the first eight; more decompositions exist.
