Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028662, here are decompositions:

83 + 1028579 = 1028662
101 + 1028561 = 1028662
191 + 1028471 = 1028662
251 + 1028411 = 1028662
269 + 1028393 = 1028662
353 + 1028309 = 1028662
359 + 1028303 = 1028662
389 + 1028273 = 1028662

Showing the first eight; more decompositions exist.
