Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022630, here are decompositions:

19 + 1022611 = 1022630
127 + 1022503 = 1022630
139 + 1022491 = 1022630
163 + 1022467 = 1022630
181 + 1022449 = 1022630
241 + 1022389 = 1022630
379 + 1022251 = 1022630
421 + 1022209 = 1022630

Showing the first eight; more decompositions exist.
