Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028288, here are decompositions:

67 + 1028221 = 1028288
97 + 1028191 = 1028288
139 + 1028149 = 1028288
181 + 1028107 = 1028288
199 + 1028089 = 1028288
241 + 1028047 = 1028288
271 + 1028017 = 1028288
277 + 1028011 = 1028288

Showing the first eight; more decompositions exist.
