Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021758, here are decompositions:

5 + 1021753 = 1021758
11 + 1021747 = 1021758
47 + 1021711 = 1021758
61 + 1021697 = 1021758
97 + 1021661 = 1021758
107 + 1021651 = 1021758
131 + 1021627 = 1021758
137 + 1021621 = 1021758

Showing the first eight; more decompositions exist.
