Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021664, here are decompositions:

3 + 1021661 = 1021664
13 + 1021651 = 1021664
37 + 1021627 = 1021664
43 + 1021621 = 1021664
103 + 1021561 = 1021664
181 + 1021483 = 1021664
223 + 1021441 = 1021664
277 + 1021387 = 1021664

Showing the first eight; more decompositions exist.
