Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13530, here are decompositions:

7 + 13523 = 13530
17 + 13513 = 13530
31 + 13499 = 13530
43 + 13487 = 13530
53 + 13477 = 13530
61 + 13469 = 13530
67 + 13463 = 13530
73 + 13457 = 13530

Showing the first eight; more decompositions exist.
