Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13266, here are decompositions:

7 + 13259 = 13266
17 + 13249 = 13266
37 + 13229 = 13266
47 + 13219 = 13266
79 + 13187 = 13266
83 + 13183 = 13266
89 + 13177 = 13266
103 + 13163 = 13266

Showing the first eight; more decompositions exist.
