Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16168, here are decompositions:

29 + 16139 = 16168
41 + 16127 = 16168
71 + 16097 = 16168
101 + 16067 = 16168
107 + 16061 = 16168
167 + 16001 = 16168
197 + 15971 = 16168
281 + 15887 = 16168

Showing the first eight; more decompositions exist.
