Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028506, here are decompositions:

113 + 1028393 = 1028506
173 + 1028333 = 1028506
179 + 1028327 = 1028506
197 + 1028309 = 1028506
233 + 1028273 = 1028506
263 + 1028243 = 1028506
293 + 1028213 = 1028506
317 + 1028189 = 1028506

Showing the first eight; more decompositions exist.
