Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997310, here are decompositions:

3 + 997307 = 997310
31 + 997279 = 997310
37 + 997273 = 997310
43 + 997267 = 997310
103 + 997207 = 997310
109 + 997201 = 997310
157 + 997153 = 997310
163 + 997147 = 997310

Showing the first eight; more decompositions exist.
