Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997358, here are decompositions:

31 + 997327 = 997358
79 + 997279 = 997358
139 + 997219 = 997358
151 + 997207 = 997358
157 + 997201 = 997358
211 + 997147 = 997358
277 + 997081 = 997358
337 + 997021 = 997358

Showing the first eight; more decompositions exist.
