Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12168, here are decompositions:

5 + 12163 = 12168
7 + 12161 = 12168
11 + 12157 = 12168
19 + 12149 = 12168
59 + 12109 = 12168
61 + 12107 = 12168
67 + 12101 = 12168
71 + 12097 = 12168

Showing the first eight; more decompositions exist.
