Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140238, here are decompositions:

11 + 140227 = 140238
17 + 140221 = 140238
31 + 140207 = 140238
41 + 140197 = 140238
47 + 140191 = 140238
61 + 140177 = 140238
67 + 140171 = 140238
71 + 140167 = 140238

Showing the first eight; more decompositions exist.
