Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997608, here are decompositions:

11 + 997597 = 997608
19 + 997589 = 997608
61 + 997547 = 997608
67 + 997541 = 997608
97 + 997511 = 997608
181 + 997427 = 997608
229 + 997379 = 997608
239 + 997369 = 997608

Showing the first eight; more decompositions exist.
