Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028224, here are decompositions:

3 + 1028221 = 1028224
11 + 1028213 = 1028224
17 + 1028207 = 1028224
23 + 1028201 = 1028224
83 + 1028141 = 1028224
107 + 1028117 = 1028224
173 + 1028051 = 1028224
293 + 1027931 = 1028224

Showing the first eight; more decompositions exist.
