Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15360, here are decompositions:

11 + 15349 = 15360
29 + 15331 = 15360
31 + 15329 = 15360
41 + 15319 = 15360
47 + 15313 = 15360
53 + 15307 = 15360
61 + 15299 = 15360
71 + 15289 = 15360

Showing the first eight; more decompositions exist.
