Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022122, here are decompositions:

89 + 1022033 = 1022122
149 + 1021973 = 1022122
449 + 1021673 = 1022122
461 + 1021661 = 1022122
659 + 1021463 = 1022122
719 + 1021403 = 1022122
821 + 1021301 = 1022122
839 + 1021283 = 1022122

Showing the first eight; more decompositions exist.
