Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022728, here are decompositions:

89 + 1022639 = 1022728
137 + 1022591 = 1022728
197 + 1022531 = 1022728
227 + 1022501 = 1022728
347 + 1022381 = 1022728
479 + 1022249 = 1022728
491 + 1022237 = 1022728
587 + 1022141 = 1022728

Showing the first eight; more decompositions exist.
