Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15282, here are decompositions:

5 + 15277 = 15282
11 + 15271 = 15282
13 + 15269 = 15282
19 + 15263 = 15282
23 + 15259 = 15282
41 + 15241 = 15282
83 + 15199 = 15282
89 + 15193 = 15282

Showing the first eight; more decompositions exist.
