Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020636, here are decompositions:

5 + 1020631 = 1020636
17 + 1020619 = 1020636
37 + 1020599 = 1020636
47 + 1020589 = 1020636
53 + 1020583 = 1020636
79 + 1020557 = 1020636
107 + 1020529 = 1020636
179 + 1020457 = 1020636

Showing the first eight; more decompositions exist.
