Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71188, here are decompositions:

17 + 71171 = 71188
41 + 71147 = 71188
59 + 71129 = 71188
107 + 71081 = 71188
149 + 71039 = 71188
191 + 70997 = 71188
197 + 70991 = 71188
239 + 70949 = 71188

Showing the first eight; more decompositions exist.
