Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38278, here are decompositions:

5 + 38273 = 38278
17 + 38261 = 38278
41 + 38237 = 38278
47 + 38231 = 38278
59 + 38219 = 38278
89 + 38189 = 38278
101 + 38177 = 38278
239 + 38039 = 38278

Showing the first eight; more decompositions exist.
