Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16836, here are decompositions:

5 + 16831 = 16836
7 + 16829 = 16836
13 + 16823 = 16836
73 + 16763 = 16836
89 + 16747 = 16836
107 + 16729 = 16836
137 + 16699 = 16836
163 + 16673 = 16836

Showing the first eight; more decompositions exist.
