Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022664, here are decompositions:

11 + 1022653 = 1022664
31 + 1022633 = 1022664
53 + 1022611 = 1022664
73 + 1022591 = 1022664
151 + 1022513 = 1022664
157 + 1022507 = 1022664
163 + 1022501 = 1022664
173 + 1022491 = 1022664

Showing the first eight; more decompositions exist.
