Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997660, here are decompositions:

11 + 997649 = 997660
23 + 997637 = 997660
71 + 997589 = 997660
107 + 997553 = 997660
113 + 997547 = 997660
149 + 997511 = 997660
197 + 997463 = 997660
227 + 997433 = 997660

Showing the first eight; more decompositions exist.
