Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13506, here are decompositions:

7 + 13499 = 13506
19 + 13487 = 13506
29 + 13477 = 13506
37 + 13469 = 13506
43 + 13463 = 13506
89 + 13417 = 13506
107 + 13399 = 13506
109 + 13397 = 13506

Showing the first eight; more decompositions exist.
