Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997040, here are decompositions:

3 + 997037 = 997040
19 + 997021 = 997040
61 + 996979 = 997040
67 + 996973 = 997040
73 + 996967 = 997040
157 + 996883 = 997040
181 + 996859 = 997040
193 + 996847 = 997040

Showing the first eight; more decompositions exist.
