Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15384, here are decompositions:

7 + 15377 = 15384
11 + 15373 = 15384
23 + 15361 = 15384
53 + 15331 = 15384
71 + 15313 = 15384
97 + 15287 = 15384
107 + 15277 = 15384
113 + 15271 = 15384

Showing the first eight; more decompositions exist.
