Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38320, here are decompositions:

3 + 38317 = 38320
17 + 38303 = 38320
47 + 38273 = 38320
59 + 38261 = 38320
83 + 38237 = 38320
89 + 38231 = 38320
101 + 38219 = 38320
131 + 38189 = 38320

Showing the first eight; more decompositions exist.
