Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140306, here are decompositions:

37 + 140269 = 140306
43 + 140263 = 140306
79 + 140227 = 140306
109 + 140197 = 140306
139 + 140167 = 140306
163 + 140143 = 140306
307 + 139999 = 140306
337 + 139969 = 140306

Showing the first eight; more decompositions exist.
