Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12276, here are decompositions:

7 + 12269 = 12276
13 + 12263 = 12276
23 + 12253 = 12276
37 + 12239 = 12276
73 + 12203 = 12276
79 + 12197 = 12276
113 + 12163 = 12276
127 + 12149 = 12276

Showing the first eight; more decompositions exist.
