Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997308, here are decompositions:

29 + 997279 = 997308
41 + 997267 = 997308
61 + 997247 = 997308
89 + 997219 = 997308
101 + 997207 = 997308
107 + 997201 = 997308
157 + 997151 = 997308
167 + 997141 = 997308

Showing the first eight; more decompositions exist.
