Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997786, here are decompositions:

3 + 997783 = 997786
17 + 997769 = 997786
47 + 997739 = 997786
59 + 997727 = 997786
137 + 997649 = 997786
149 + 997637 = 997786
197 + 997589 = 997786
233 + 997553 = 997786

Showing the first eight; more decompositions exist.
