Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997966, here are decompositions:

3 + 997963 = 997966
5 + 997961 = 997966
17 + 997949 = 997966
89 + 997877 = 997966
173 + 997793 = 997966
197 + 997769 = 997966
227 + 997739 = 997966
239 + 997727 = 997966

Showing the first eight; more decompositions exist.
