Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15324, here are decompositions:

5 + 15319 = 15324
11 + 15313 = 15324
17 + 15307 = 15324
37 + 15287 = 15324
47 + 15277 = 15324
53 + 15271 = 15324
61 + 15263 = 15324
83 + 15241 = 15324

Showing the first eight; more decompositions exist.
