Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997490, here are decompositions:

37 + 997453 = 997490
157 + 997333 = 997490
163 + 997327 = 997490
181 + 997309 = 997490
211 + 997279 = 997490
223 + 997267 = 997490
271 + 997219 = 997490
283 + 997207 = 997490

Showing the first eight; more decompositions exist.
