Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12306, here are decompositions:

5 + 12301 = 12306
17 + 12289 = 12306
29 + 12277 = 12306
37 + 12269 = 12306
43 + 12263 = 12306
53 + 12253 = 12306
67 + 12239 = 12306
79 + 12227 = 12306

Showing the first eight; more decompositions exist.
