Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997486, here are decompositions:

23 + 997463 = 997486
47 + 997439 = 997486
53 + 997433 = 997486
59 + 997427 = 997486
107 + 997379 = 997486
167 + 997319 = 997486
179 + 997307 = 997486
227 + 997259 = 997486

Showing the first eight; more decompositions exist.
