Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13306, here are decompositions:

47 + 13259 = 13306
89 + 13217 = 13306
179 + 13127 = 13306
197 + 13109 = 13306
257 + 13049 = 13306
263 + 13043 = 13306
269 + 13037 = 13306
347 + 12959 = 13306

Showing the first eight; more decompositions exist.
