Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140228, here are decompositions:

7 + 140221 = 140228
31 + 140197 = 140228
37 + 140191 = 140228
61 + 140167 = 140228
157 + 140071 = 140228
229 + 139999 = 140228
241 + 139987 = 140228
307 + 139921 = 140228

Showing the first eight; more decompositions exist.
