Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028470, here are decompositions:

59 + 1028411 = 1028470
137 + 1028333 = 1028470
167 + 1028303 = 1028470
197 + 1028273 = 1028470
227 + 1028243 = 1028470
239 + 1028231 = 1028470
257 + 1028213 = 1028470
263 + 1028207 = 1028470

Showing the first eight; more decompositions exist.
