Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021770, here are decompositions:

11 + 1021759 = 1021770
17 + 1021753 = 1021770
23 + 1021747 = 1021770
59 + 1021711 = 1021770
73 + 1021697 = 1021770
97 + 1021673 = 1021770
107 + 1021663 = 1021770
109 + 1021661 = 1021770

Showing the first eight; more decompositions exist.
