Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021098, here are decompositions:

5 + 1021093 = 1021098
7 + 1021091 = 1021098
11 + 1021087 = 1021098
17 + 1021081 = 1021098
31 + 1021067 = 1021098
79 + 1021019 = 1021098
97 + 1021001 = 1021098
101 + 1020997 = 1021098

Showing the first eight; more decompositions exist.
