Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39388, here are decompositions:

5 + 39383 = 39388
17 + 39371 = 39388
29 + 39359 = 39388
47 + 39341 = 39388
71 + 39317 = 39388
137 + 39251 = 39388
149 + 39239 = 39388
179 + 39209 = 39388

Showing the first eight; more decompositions exist.
