Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13260, here are decompositions:

11 + 13249 = 13260
19 + 13241 = 13260
31 + 13229 = 13260
41 + 13219 = 13260
43 + 13217 = 13260
73 + 13187 = 13260
83 + 13177 = 13260
89 + 13171 = 13260

Showing the first eight; more decompositions exist.
