Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12210, here are decompositions:

7 + 12203 = 12210
13 + 12197 = 12210
47 + 12163 = 12210
53 + 12157 = 12210
61 + 12149 = 12210
67 + 12143 = 12210
97 + 12113 = 12210
101 + 12109 = 12210

Showing the first eight; more decompositions exist.
