Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15238, here are decompositions:

5 + 15233 = 15238
11 + 15227 = 15238
89 + 15149 = 15238
101 + 15137 = 15238
107 + 15131 = 15238
131 + 15107 = 15238
137 + 15101 = 15238
269 + 14969 = 15238

Showing the first eight; more decompositions exist.
