Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997556, here are decompositions:

3 + 997553 = 997556
103 + 997453 = 997556
199 + 997357 = 997556
223 + 997333 = 997556
229 + 997327 = 997556
277 + 997279 = 997556
283 + 997273 = 997556
337 + 997219 = 997556

Showing the first eight; more decompositions exist.
