Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140138, here are decompositions:

67 + 140071 = 140138
139 + 139999 = 140138
151 + 139987 = 140138
157 + 139981 = 140138
199 + 139939 = 140138
277 + 139861 = 140138
307 + 139831 = 140138
337 + 139801 = 140138

Showing the first eight; more decompositions exist.
