Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021422, here are decompositions:

5 + 1021417 = 1021422
19 + 1021403 = 1021422
41 + 1021381 = 1021422
53 + 1021369 = 1021422
89 + 1021333 = 1021422
131 + 1021291 = 1021422
139 + 1021283 = 1021422
151 + 1021271 = 1021422

Showing the first eight; more decompositions exist.
