Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13248, here are decompositions:

7 + 13241 = 13248
19 + 13229 = 13248
29 + 13219 = 13248
31 + 13217 = 13248
61 + 13187 = 13248
71 + 13177 = 13248
89 + 13159 = 13248
97 + 13151 = 13248

Showing the first eight; more decompositions exist.
