Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997788, here are decompositions:

5 + 997783 = 997788
19 + 997769 = 997788
37 + 997751 = 997788
47 + 997741 = 997788
61 + 997727 = 997788
89 + 997699 = 997788
107 + 997681 = 997788
137 + 997651 = 997788

Showing the first eight; more decompositions exist.
