Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002656, here are decompositions:

3 + 1002653 = 1002656
37 + 1002619 = 1002656
73 + 1002583 = 1002656
79 + 1002577 = 1002656
103 + 1002553 = 1002656
139 + 1002517 = 1002656
163 + 1002493 = 1002656
199 + 1002457 = 1002656

Showing the first eight; more decompositions exist.
