Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38800, here are decompositions:

17 + 38783 = 38800
53 + 38747 = 38800
71 + 38729 = 38800
89 + 38711 = 38800
101 + 38699 = 38800
107 + 38693 = 38800
131 + 38669 = 38800
149 + 38651 = 38800

Showing the first eight; more decompositions exist.
