Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13436, here are decompositions:

19 + 13417 = 13436
37 + 13399 = 13436
97 + 13339 = 13436
109 + 13327 = 13436
127 + 13309 = 13436
139 + 13297 = 13436
277 + 13159 = 13436
337 + 13099 = 13436

Showing the first eight; more decompositions exist.
