Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028308, here are decompositions:

5 + 1028303 = 1028308
101 + 1028207 = 1028308
107 + 1028201 = 1028308
167 + 1028141 = 1028308
179 + 1028129 = 1028308
191 + 1028117 = 1028308
227 + 1028081 = 1028308
257 + 1028051 = 1028308

Showing the first eight; more decompositions exist.
