Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15408, here are decompositions:

7 + 15401 = 15408
17 + 15391 = 15408
31 + 15377 = 15408
47 + 15361 = 15408
59 + 15349 = 15408
79 + 15329 = 15408
89 + 15319 = 15408
101 + 15307 = 15408

Showing the first eight; more decompositions exist.
