Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997768, here are decompositions:

17 + 997751 = 997768
29 + 997739 = 997768
41 + 997727 = 997768
131 + 997637 = 997768
179 + 997589 = 997768
227 + 997541 = 997768
257 + 997511 = 997768
389 + 997379 = 997768

Showing the first eight; more decompositions exist.
