Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997318, here are decompositions:

11 + 997307 = 997318
59 + 997259 = 997318
71 + 997247 = 997318
167 + 997151 = 997318
197 + 997121 = 997318
227 + 997091 = 997318
281 + 997037 = 997318
317 + 997001 = 997318

Showing the first eight; more decompositions exist.
