Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020630, here are decompositions:

11 + 1020619 = 1020630
31 + 1020599 = 1020630
41 + 1020589 = 1020630
47 + 1020583 = 1020630
73 + 1020557 = 1020630
89 + 1020541 = 1020630
101 + 1020529 = 1020630
113 + 1020517 = 1020630

Showing the first eight; more decompositions exist.
