Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021028, here are decompositions:

31 + 1020997 = 1021028
37 + 1020991 = 1021028
61 + 1020967 = 1021028
67 + 1020961 = 1021028
97 + 1020931 = 1021028
181 + 1020847 = 1021028
271 + 1020757 = 1021028
277 + 1020751 = 1021028

Showing the first eight; more decompositions exist.
