Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020858, here are decompositions:

5 + 1020853 = 1020858
11 + 1020847 = 1020858
17 + 1020841 = 1020858
19 + 1020839 = 1020858
31 + 1020827 = 1020858
37 + 1020821 = 1020858
61 + 1020797 = 1020858
79 + 1020779 = 1020858

Showing the first eight; more decompositions exist.
