Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12270, here are decompositions:

7 + 12263 = 12270
17 + 12253 = 12270
19 + 12251 = 12270
29 + 12241 = 12270
31 + 12239 = 12270
43 + 12227 = 12270
59 + 12211 = 12270
67 + 12203 = 12270

Showing the first eight; more decompositions exist.
