Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17816, here are decompositions:

67 + 17749 = 17816
79 + 17737 = 17816
103 + 17713 = 17816
109 + 17707 = 17816
157 + 17659 = 17816
193 + 17623 = 17816
277 + 17539 = 17816
307 + 17509 = 17816

Showing the first eight; more decompositions exist.
