Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021022, here are decompositions:

3 + 1021019 = 1021022
31 + 1020991 = 1021022
43 + 1020979 = 1021022
61 + 1020961 = 1021022
109 + 1020913 = 1021022
181 + 1020841 = 1021022
199 + 1020823 = 1021022
271 + 1020751 = 1021022

Showing the first eight; more decompositions exist.
