Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997806, here are decompositions:

13 + 997793 = 997806
23 + 997783 = 997806
37 + 997769 = 997806
67 + 997739 = 997806
79 + 997727 = 997806
107 + 997699 = 997806
113 + 997693 = 997806
157 + 997649 = 997806

Showing the first eight; more decompositions exist.
