Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16840, here are decompositions:

11 + 16829 = 16840
17 + 16823 = 16840
29 + 16811 = 16840
53 + 16787 = 16840
137 + 16703 = 16840
149 + 16691 = 16840
167 + 16673 = 16840
179 + 16661 = 16840

Showing the first eight; more decompositions exist.
