Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028436, here are decompositions:

43 + 1028393 = 1028436
47 + 1028389 = 1028436
103 + 1028333 = 1028436
107 + 1028329 = 1028436
109 + 1028327 = 1028436
127 + 1028309 = 1028436
163 + 1028273 = 1028436
173 + 1028263 = 1028436

Showing the first eight; more decompositions exist.
