Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16138, here are decompositions:

11 + 16127 = 16138
41 + 16097 = 16138
47 + 16091 = 16138
71 + 16067 = 16138
131 + 16007 = 16138
137 + 16001 = 16138
167 + 15971 = 16138
179 + 15959 = 16138

Showing the first eight; more decompositions exist.
