Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028460, here are decompositions:

23 + 1028437 = 1028460
67 + 1028393 = 1028460
71 + 1028389 = 1028460
127 + 1028333 = 1028460
131 + 1028329 = 1028460
151 + 1028309 = 1028460
157 + 1028303 = 1028460
197 + 1028263 = 1028460

Showing the first eight; more decompositions exist.
