Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997418, here are decompositions:

61 + 997357 = 997418
109 + 997309 = 997418
139 + 997279 = 997418
151 + 997267 = 997418
199 + 997219 = 997418
211 + 997207 = 997418
271 + 997147 = 997418
277 + 997141 = 997418

Showing the first eight; more decompositions exist.
