Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15258, here are decompositions:

17 + 15241 = 15258
31 + 15227 = 15258
41 + 15217 = 15258
59 + 15199 = 15258
71 + 15187 = 15258
97 + 15161 = 15258
109 + 15149 = 15258
127 + 15131 = 15258

Showing the first eight; more decompositions exist.
