Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020642, here are decompositions:

11 + 1020631 = 1020642
23 + 1020619 = 1020642
43 + 1020599 = 1020642
53 + 1020589 = 1020642
59 + 1020583 = 1020642
101 + 1020541 = 1020642
113 + 1020529 = 1020642
151 + 1020491 = 1020642

Showing the first eight; more decompositions exist.
