Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13270, here are decompositions:

3 + 13267 = 13270
11 + 13259 = 13270
29 + 13241 = 13270
41 + 13229 = 13270
53 + 13217 = 13270
83 + 13187 = 13270
107 + 13163 = 13270
149 + 13121 = 13270

Showing the first eight; more decompositions exist.
