Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997836, here are decompositions:

23 + 997813 = 997836
29 + 997807 = 997836
43 + 997793 = 997836
53 + 997783 = 997836
67 + 997769 = 997836
97 + 997739 = 997836
109 + 997727 = 997836
137 + 997699 = 997836

Showing the first eight; more decompositions exist.
