Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15310, here are decompositions:

3 + 15307 = 15310
11 + 15299 = 15310
23 + 15287 = 15310
41 + 15269 = 15310
47 + 15263 = 15310
83 + 15227 = 15310
137 + 15173 = 15310
149 + 15161 = 15310

Showing the first eight; more decompositions exist.
