Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8188, here are decompositions:

17 + 8171 = 8188
41 + 8147 = 8188
71 + 8117 = 8188
101 + 8087 = 8188
107 + 8081 = 8188
149 + 8039 = 8188
179 + 8009 = 8188
239 + 7949 = 8188

Showing the first eight; more decompositions exist.
