Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16918, here are decompositions:

17 + 16901 = 16918
29 + 16889 = 16918
47 + 16871 = 16918
89 + 16829 = 16918
107 + 16811 = 16918
131 + 16787 = 16918
227 + 16691 = 16918
257 + 16661 = 16918

Showing the first eight; more decompositions exist.
