Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020650, here are decompositions:

19 + 1020631 = 1020650
31 + 1020619 = 1020650
61 + 1020589 = 1020650
67 + 1020583 = 1020650
109 + 1020541 = 1020650
193 + 1020457 = 1020650
199 + 1020451 = 1020650
271 + 1020379 = 1020650

Showing the first eight; more decompositions exist.
