Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021668, here are decompositions:

5 + 1021663 = 1021668
7 + 1021661 = 1021668
17 + 1021651 = 1021668
41 + 1021627 = 1021668
47 + 1021621 = 1021668
97 + 1021571 = 1021668
107 + 1021561 = 1021668
127 + 1021541 = 1021668

Showing the first eight; more decompositions exist.
