Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997774, here are decompositions:

5 + 997769 = 997774
23 + 997751 = 997774
47 + 997727 = 997774
137 + 997637 = 997774
191 + 997583 = 997774
227 + 997547 = 997774
233 + 997541 = 997774
263 + 997511 = 997774

Showing the first eight; more decompositions exist.
