Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021776, here are decompositions:

17 + 1021759 = 1021776
23 + 1021753 = 1021776
29 + 1021747 = 1021776
79 + 1021697 = 1021776
103 + 1021673 = 1021776
113 + 1021663 = 1021776
149 + 1021627 = 1021776
199 + 1021577 = 1021776

Showing the first eight; more decompositions exist.
