Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140256, here are decompositions:

7 + 140249 = 140256
19 + 140237 = 140256
29 + 140227 = 140256
59 + 140197 = 140256
79 + 140177 = 140256
89 + 140167 = 140256
97 + 140159 = 140256
113 + 140143 = 140256

Showing the first eight; more decompositions exist.
