Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13600, here are decompositions:

3 + 13597 = 13600
23 + 13577 = 13600
47 + 13553 = 13600
101 + 13499 = 13600
113 + 13487 = 13600
131 + 13469 = 13600
137 + 13463 = 13600
149 + 13451 = 13600

Showing the first eight; more decompositions exist.
