Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028668, here are decompositions:

5 + 1028663 = 1028668
71 + 1028597 = 1028668
89 + 1028579 = 1028668
107 + 1028561 = 1028668
197 + 1028471 = 1028668
257 + 1028411 = 1028668
359 + 1028309 = 1028668
461 + 1028207 = 1028668

Showing the first eight; more decompositions exist.
