Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140298, here are decompositions:

17 + 140281 = 140298
29 + 140269 = 140298
61 + 140237 = 140298
71 + 140227 = 140298
101 + 140197 = 140298
107 + 140191 = 140298
127 + 140171 = 140298
131 + 140167 = 140298

Showing the first eight; more decompositions exist.
