Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997798, here are decompositions:

5 + 997793 = 997798
29 + 997769 = 997798
47 + 997751 = 997798
59 + 997739 = 997798
71 + 997727 = 997798
149 + 997649 = 997798
251 + 997547 = 997798
257 + 997541 = 997798

Showing the first eight; more decompositions exist.
