Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12212, here are decompositions:

103 + 12109 = 12212
139 + 12073 = 12212
163 + 12049 = 12212
241 + 11971 = 12212
271 + 11941 = 12212
349 + 11863 = 12212
373 + 11839 = 12212
379 + 11833 = 12212

Showing the first eight; more decompositions exist.
