Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11786, here are decompositions:

3 + 11783 = 11786
7 + 11779 = 11786
43 + 11743 = 11786
67 + 11719 = 11786
97 + 11689 = 11786
109 + 11677 = 11786
193 + 11593 = 11786
199 + 11587 = 11786

Showing the first eight; more decompositions exist.
