Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997776, here are decompositions:

7 + 997769 = 997776
37 + 997739 = 997776
83 + 997693 = 997776
113 + 997663 = 997776
127 + 997649 = 997776
139 + 997637 = 997776
149 + 997627 = 997776
167 + 997609 = 997776

Showing the first eight; more decompositions exist.
