Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140258, here are decompositions:

31 + 140227 = 140258
37 + 140221 = 140258
61 + 140197 = 140258
67 + 140191 = 140258
271 + 139987 = 140258
277 + 139981 = 140258
337 + 139921 = 140258
367 + 139891 = 140258

Showing the first eight; more decompositions exist.
