Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13566, here are decompositions:

13 + 13553 = 13566
29 + 13537 = 13566
43 + 13523 = 13566
53 + 13513 = 13566
67 + 13499 = 13566
79 + 13487 = 13566
89 + 13477 = 13566
97 + 13469 = 13566

Showing the first eight; more decompositions exist.
