Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997690, here are decompositions:

41 + 997649 = 997690
53 + 997637 = 997690
101 + 997589 = 997690
107 + 997583 = 997690
137 + 997553 = 997690
149 + 997541 = 997690
179 + 997511 = 997690
227 + 997463 = 997690

Showing the first eight; more decompositions exist.
