Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130266, here are decompositions:

5 + 130261 = 130266
7 + 130259 = 130266
13 + 130253 = 130266
43 + 130223 = 130266
67 + 130199 = 130266
83 + 130183 = 130266
139 + 130127 = 130266
167 + 130099 = 130266

Showing the first eight; more decompositions exist.
