Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020998, here are decompositions:

7 + 1020991 = 1020998
19 + 1020979 = 1020998
31 + 1020967 = 1020998
37 + 1020961 = 1020998
67 + 1020931 = 1020998
151 + 1020847 = 1020998
157 + 1020841 = 1020998
241 + 1020757 = 1020998

Showing the first eight; more decompositions exist.
