Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102266, here are decompositions:

7 + 102259 = 102266
13 + 102253 = 102266
37 + 102229 = 102266
67 + 102199 = 102266
127 + 102139 = 102266
163 + 102103 = 102266
223 + 102043 = 102266
337 + 101929 = 102266

Showing the first eight; more decompositions exist.
