Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028340, here are decompositions:

7 + 1028333 = 1028340
11 + 1028329 = 1028340
13 + 1028327 = 1028340
23 + 1028317 = 1028340
31 + 1028309 = 1028340
37 + 1028303 = 1028340
67 + 1028273 = 1028340
97 + 1028243 = 1028340

Showing the first eight; more decompositions exist.
