Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997554, here are decompositions:

7 + 997547 = 997554
13 + 997541 = 997554
43 + 997511 = 997554
101 + 997453 = 997554
127 + 997427 = 997554
163 + 997391 = 997554
197 + 997357 = 997554
211 + 997343 = 997554

Showing the first eight; more decompositions exist.
