Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140208, here are decompositions:

11 + 140197 = 140208
17 + 140191 = 140208
31 + 140177 = 140208
37 + 140171 = 140208
41 + 140167 = 140208
97 + 140111 = 140208
137 + 140071 = 140208
139 + 140069 = 140208

Showing the first eight; more decompositions exist.
