Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997020, here are decompositions:

7 + 997013 = 997020
19 + 997001 = 997020
41 + 996979 = 997020
47 + 996973 = 997020
53 + 996967 = 997020
67 + 996953 = 997020
137 + 996883 = 997020
139 + 996881 = 997020

Showing the first eight; more decompositions exist.
