Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997022, here are decompositions:

3 + 997019 = 997022
43 + 996979 = 997022
139 + 996883 = 997022
151 + 996871 = 997022
163 + 996859 = 997022
181 + 996841 = 997022
211 + 996811 = 997022
241 + 996781 = 997022

Showing the first eight; more decompositions exist.
