Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997474, here are decompositions:

11 + 997463 = 997474
41 + 997433 = 997474
47 + 997427 = 997474
83 + 997391 = 997474
131 + 997343 = 997474
167 + 997307 = 997474
227 + 997247 = 997474
311 + 997163 = 997474

Showing the first eight; more decompositions exist.
