Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38542, here are decompositions:

41 + 38501 = 38542
83 + 38459 = 38542
89 + 38453 = 38542
149 + 38393 = 38542
191 + 38351 = 38542
239 + 38303 = 38542
269 + 38273 = 38542
281 + 38261 = 38542

Showing the first eight; more decompositions exist.
