Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3258, here are decompositions:

5 + 3253 = 3258
7 + 3251 = 3258
29 + 3229 = 3258
37 + 3221 = 3258
41 + 3217 = 3258
67 + 3191 = 3258
71 + 3187 = 3258
89 + 3169 = 3258

Showing the first eight; more decompositions exist.
