Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008656, here are decompositions:

43 + 1008613 = 1008656
67 + 1008589 = 1008656
109 + 1008547 = 1008656
139 + 1008517 = 1008656
157 + 1008499 = 1008656
163 + 1008493 = 1008656
223 + 1008433 = 1008656
277 + 1008379 = 1008656

Showing the first eight; more decompositions exist.
