Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028266, here are decompositions:

3 + 1028263 = 1028266
23 + 1028243 = 1028266
53 + 1028213 = 1028266
59 + 1028207 = 1028266
137 + 1028129 = 1028266
149 + 1028117 = 1028266
167 + 1028099 = 1028266
263 + 1028003 = 1028266

Showing the first eight; more decompositions exist.
