Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997080, here are decompositions:

11 + 997069 = 997080
23 + 997057 = 997080
37 + 997043 = 997080
43 + 997037 = 997080
59 + 997021 = 997080
61 + 997019 = 997080
67 + 997013 = 997080
79 + 997001 = 997080

Showing the first eight; more decompositions exist.
