Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17138, here are decompositions:

31 + 17107 = 17138
61 + 17077 = 17138
97 + 17041 = 17138
109 + 17029 = 17138
127 + 17011 = 17138
151 + 16987 = 17138
157 + 16981 = 17138
211 + 16927 = 17138

Showing the first eight; more decompositions exist.
