Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16218, here are decompositions:

29 + 16189 = 16218
31 + 16187 = 16218
79 + 16139 = 16218
107 + 16111 = 16218
127 + 16091 = 16218
131 + 16087 = 16218
149 + 16069 = 16218
151 + 16067 = 16218

Showing the first eight; more decompositions exist.
