Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13258, here are decompositions:

17 + 13241 = 13258
29 + 13229 = 13258
41 + 13217 = 13258
71 + 13187 = 13258
107 + 13151 = 13258
131 + 13127 = 13258
137 + 13121 = 13258
149 + 13109 = 13258

Showing the first eight; more decompositions exist.
