Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997288, here are decompositions:

29 + 997259 = 997288
41 + 997247 = 997288
137 + 997151 = 997288
167 + 997121 = 997288
179 + 997109 = 997288
191 + 997097 = 997288
197 + 997091 = 997288
251 + 997037 = 997288

Showing the first eight; more decompositions exist.
