Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028478, here are decompositions:

5 + 1028473 = 1028478
7 + 1028471 = 1028478
41 + 1028437 = 1028478
67 + 1028411 = 1028478
89 + 1028389 = 1028478
149 + 1028329 = 1028478
151 + 1028327 = 1028478
257 + 1028221 = 1028478

Showing the first eight; more decompositions exist.
