Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38540, here are decompositions:

79 + 38461 = 38540
109 + 38431 = 38540
163 + 38377 = 38540
211 + 38329 = 38540
223 + 38317 = 38540
241 + 38299 = 38540
373 + 38167 = 38540
421 + 38119 = 38540

Showing the first eight; more decompositions exist.
