Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997828, here are decompositions:

17 + 997811 = 997828
59 + 997769 = 997828
89 + 997739 = 997828
101 + 997727 = 997828
179 + 997649 = 997828
191 + 997637 = 997828
239 + 997589 = 997828
281 + 997547 = 997828

Showing the first eight; more decompositions exist.
