Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40138, here are decompositions:

11 + 40127 = 40138
101 + 40037 = 40138
107 + 40031 = 40138
149 + 39989 = 40138
167 + 39971 = 40138
251 + 39887 = 40138
269 + 39869 = 40138
281 + 39857 = 40138

Showing the first eight; more decompositions exist.
