Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997550, here are decompositions:

3 + 997547 = 997550
97 + 997453 = 997550
181 + 997369 = 997550
193 + 997357 = 997550
223 + 997327 = 997550
241 + 997309 = 997550
271 + 997279 = 997550
277 + 997273 = 997550

Showing the first eight; more decompositions exist.
