Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043664, here are decompositions:

7 + 1043657 = 1043664
47 + 1043617 = 1043664
67 + 1043597 = 1043664
71 + 1043593 = 1043664
73 + 1043591 = 1043664
107 + 1043557 = 1043664
151 + 1043513 = 1043664
163 + 1043501 = 1043664

Showing the first eight; more decompositions exist.
