Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140456, here are decompositions:

3 + 140453 = 140456
7 + 140449 = 140456
13 + 140443 = 140456
37 + 140419 = 140456
139 + 140317 = 140456
193 + 140263 = 140456
229 + 140227 = 140456
313 + 140143 = 140456

Showing the first eight; more decompositions exist.
