Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12226, here are decompositions:

23 + 12203 = 12226
29 + 12197 = 12226
83 + 12143 = 12226
107 + 12119 = 12226
113 + 12113 = 12226
239 + 11987 = 12226
257 + 11969 = 12226
293 + 11933 = 12226

Showing the first eight; more decompositions exist.
