Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997558, here are decompositions:

5 + 997553 = 997558
11 + 997547 = 997558
17 + 997541 = 997558
47 + 997511 = 997558
131 + 997427 = 997558
167 + 997391 = 997558
179 + 997379 = 997558
239 + 997319 = 997558

Showing the first eight; more decompositions exist.
