Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65188, here are decompositions:

5 + 65183 = 65188
17 + 65171 = 65188
41 + 65147 = 65188
47 + 65141 = 65188
59 + 65129 = 65188
89 + 65099 = 65188
191 + 64997 = 65188
251 + 64937 = 65188

Showing the first eight; more decompositions exist.
