Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028228, here are decompositions:

7 + 1028221 = 1028228
37 + 1028191 = 1028228
79 + 1028149 = 1028228
127 + 1028101 = 1028228
139 + 1028089 = 1028228
181 + 1028047 = 1028228
199 + 1028029 = 1028228
211 + 1028017 = 1028228

Showing the first eight; more decompositions exist.
