Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997800, here are decompositions:

7 + 997793 = 997800
17 + 997783 = 997800
31 + 997769 = 997800
59 + 997741 = 997800
61 + 997739 = 997800
73 + 997727 = 997800
101 + 997699 = 997800
107 + 997693 = 997800

Showing the first eight; more decompositions exist.
