Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005656, here are decompositions:

13 + 1005643 = 1005656
19 + 1005637 = 1005656
37 + 1005619 = 1005656
103 + 1005553 = 1005656
163 + 1005493 = 1005656
199 + 1005457 = 1005656
229 + 1005427 = 1005656
283 + 1005373 = 1005656

Showing the first eight; more decompositions exist.
