Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028560, here are decompositions:

3 + 1028557 = 1028560
89 + 1028471 = 1028560
149 + 1028411 = 1028560
167 + 1028393 = 1028560
227 + 1028333 = 1028560
233 + 1028327 = 1028560
251 + 1028309 = 1028560
257 + 1028303 = 1028560

Showing the first eight; more decompositions exist.
