Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997812, here are decompositions:

5 + 997807 = 997812
19 + 997793 = 997812
29 + 997783 = 997812
43 + 997769 = 997812
61 + 997751 = 997812
71 + 997741 = 997812
73 + 997739 = 997812
113 + 997699 = 997812

Showing the first eight; more decompositions exist.
