Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997822, here are decompositions:

11 + 997811 = 997822
29 + 997793 = 997822
53 + 997769 = 997822
71 + 997751 = 997822
83 + 997739 = 997822
173 + 997649 = 997822
233 + 997589 = 997822
239 + 997583 = 997822

Showing the first eight; more decompositions exist.
