Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028550, here are decompositions:

41 + 1028509 = 1028550
71 + 1028479 = 1028550
79 + 1028471 = 1028550
113 + 1028437 = 1028550
139 + 1028411 = 1028550
157 + 1028393 = 1028550
223 + 1028327 = 1028550
233 + 1028317 = 1028550

Showing the first eight; more decompositions exist.
