Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12286, here are decompositions:

5 + 12281 = 12286
17 + 12269 = 12286
23 + 12263 = 12286
47 + 12239 = 12286
59 + 12227 = 12286
83 + 12203 = 12286
89 + 12197 = 12286
137 + 12149 = 12286

Showing the first eight; more decompositions exist.
