Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028328, here are decompositions:

11 + 1028317 = 1028328
19 + 1028309 = 1028328
97 + 1028231 = 1028328
107 + 1028221 = 1028328
127 + 1028201 = 1028328
137 + 1028191 = 1028328
139 + 1028189 = 1028328
179 + 1028149 = 1028328

Showing the first eight; more decompositions exist.
