Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12256, here are decompositions:

3 + 12253 = 12256
5 + 12251 = 12256
17 + 12239 = 12256
29 + 12227 = 12256
53 + 12203 = 12256
59 + 12197 = 12256
107 + 12149 = 12256
113 + 12143 = 12256

Showing the first eight; more decompositions exist.
