Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12258, here are decompositions:

5 + 12253 = 12258
7 + 12251 = 12258
17 + 12241 = 12258
19 + 12239 = 12258
31 + 12227 = 12258
47 + 12211 = 12258
61 + 12197 = 12258
97 + 12161 = 12258

Showing the first eight; more decompositions exist.
