Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028446, here are decompositions:

53 + 1028393 = 1028446
113 + 1028333 = 1028446
137 + 1028309 = 1028446
173 + 1028273 = 1028446
233 + 1028213 = 1028446
239 + 1028207 = 1028446
257 + 1028189 = 1028446
317 + 1028129 = 1028446

Showing the first eight; more decompositions exist.
