Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42208, here are decompositions:

11 + 42197 = 42208
29 + 42179 = 42208
107 + 42101 = 42208
137 + 42071 = 42208
191 + 42017 = 42208
227 + 41981 = 42208
239 + 41969 = 42208
251 + 41957 = 42208

Showing the first eight; more decompositions exist.
