Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000556, here are decompositions:

19 + 1000537 = 1000556
103 + 1000453 = 1000556
127 + 1000429 = 1000556
163 + 1000393 = 1000556
199 + 1000357 = 1000556
223 + 1000333 = 1000556
283 + 1000273 = 1000556
307 + 1000249 = 1000556

Showing the first eight; more decompositions exist.
