Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38140, here are decompositions:

71 + 38069 = 38140
101 + 38039 = 38140
149 + 37991 = 38140
173 + 37967 = 38140
233 + 37907 = 38140
251 + 37889 = 38140
269 + 37871 = 38140
293 + 37847 = 38140

Showing the first eight; more decompositions exist.
