Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028406, here are decompositions:

13 + 1028393 = 1028406
17 + 1028389 = 1028406
73 + 1028333 = 1028406
79 + 1028327 = 1028406
89 + 1028317 = 1028406
97 + 1028309 = 1028406
103 + 1028303 = 1028406
163 + 1028243 = 1028406

Showing the first eight; more decompositions exist.
