Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16786, here are decompositions:

23 + 16763 = 16786
83 + 16703 = 16786
113 + 16673 = 16786
137 + 16649 = 16786
167 + 16619 = 16786
179 + 16607 = 16786
233 + 16553 = 16786
239 + 16547 = 16786

Showing the first eight; more decompositions exist.
