Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140390, here are decompositions:

73 + 140317 = 140390
109 + 140281 = 140390
127 + 140263 = 140390
163 + 140227 = 140390
193 + 140197 = 140390
199 + 140191 = 140390
223 + 140167 = 140390
337 + 140053 = 140390

Showing the first eight; more decompositions exist.
