Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997738, here are decompositions:

11 + 997727 = 997738
89 + 997649 = 997738
101 + 997637 = 997738
149 + 997589 = 997738
191 + 997547 = 997738
197 + 997541 = 997738
227 + 997511 = 997738
311 + 997427 = 997738

Showing the first eight; more decompositions exist.
