Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16166, here are decompositions:

79 + 16087 = 16166
97 + 16069 = 16166
103 + 16063 = 16166
109 + 16057 = 16166
193 + 15973 = 16166
229 + 15937 = 16166
277 + 15889 = 16166
307 + 15859 = 16166

Showing the first eight; more decompositions exist.
