Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12222, here are decompositions:

11 + 12211 = 12222
19 + 12203 = 12222
59 + 12163 = 12222
61 + 12161 = 12222
73 + 12149 = 12222
79 + 12143 = 12222
103 + 12119 = 12222
109 + 12113 = 12222

Showing the first eight; more decompositions exist.
