Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997888, here are decompositions:

11 + 997877 = 997888
137 + 997751 = 997888
149 + 997739 = 997888
239 + 997649 = 997888
251 + 997637 = 997888
347 + 997541 = 997888
449 + 997439 = 997888
461 + 997427 = 997888

Showing the first eight; more decompositions exist.
