Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8388, here are decompositions:

11 + 8377 = 8388
19 + 8369 = 8388
59 + 8329 = 8388
71 + 8317 = 8388
97 + 8291 = 8388
101 + 8287 = 8388
151 + 8237 = 8388
157 + 8231 = 8388

Showing the first eight; more decompositions exist.
