Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12266, here are decompositions:

3 + 12263 = 12266
13 + 12253 = 12266
103 + 12163 = 12266
109 + 12157 = 12266
157 + 12109 = 12266
193 + 12073 = 12266
223 + 12043 = 12266
229 + 12037 = 12266

Showing the first eight; more decompositions exist.
