Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108786, here are decompositions:

17 + 108769 = 108786
47 + 108739 = 108786
59 + 108727 = 108786
79 + 108707 = 108786
109 + 108677 = 108786
137 + 108649 = 108786
149 + 108637 = 108786
199 + 108587 = 108786

Showing the first eight; more decompositions exist.
