Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997424, here are decompositions:

67 + 997357 = 997424
97 + 997327 = 997424
151 + 997273 = 997424
157 + 997267 = 997424
223 + 997201 = 997424
271 + 997153 = 997424
277 + 997147 = 997424
283 + 997141 = 997424

Showing the first eight; more decompositions exist.
