Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028928, here are decompositions:

151 + 1028777 = 1028928
167 + 1028761 = 1028928
179 + 1028749 = 1028928
181 + 1028747 = 1028928
191 + 1028737 = 1028928
281 + 1028647 = 1028928
311 + 1028617 = 1028928
331 + 1028597 = 1028928

Showing the first eight; more decompositions exist.
