Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18212, here are decompositions:

13 + 18199 = 18212
31 + 18181 = 18212
43 + 18169 = 18212
79 + 18133 = 18212
151 + 18061 = 18212
163 + 18049 = 18212
199 + 18013 = 18212
223 + 17989 = 18212

Showing the first eight; more decompositions exist.
