Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15424, here are decompositions:

11 + 15413 = 15424
23 + 15401 = 15424
41 + 15383 = 15424
47 + 15377 = 15424
137 + 15287 = 15424
191 + 15233 = 15424
197 + 15227 = 15424
251 + 15173 = 15424

Showing the first eight; more decompositions exist.
