Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997498, here are decompositions:

59 + 997439 = 997498
71 + 997427 = 997498
107 + 997391 = 997498
179 + 997319 = 997498
191 + 997307 = 997498
239 + 997259 = 997498
251 + 997247 = 997498
347 + 997151 = 997498

Showing the first eight; more decompositions exist.
