Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997678, here are decompositions:

29 + 997649 = 997678
41 + 997637 = 997678
89 + 997589 = 997678
131 + 997547 = 997678
137 + 997541 = 997678
167 + 997511 = 997678
239 + 997439 = 997678
251 + 997427 = 997678

Showing the first eight; more decompositions exist.
