Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021650, here are decompositions:

23 + 1021627 = 1021650
29 + 1021621 = 1021650
73 + 1021577 = 1021650
79 + 1021571 = 1021650
89 + 1021561 = 1021650
109 + 1021541 = 1021650
163 + 1021487 = 1021650
167 + 1021483 = 1021650

Showing the first eight; more decompositions exist.
