Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13660, here are decompositions:

11 + 13649 = 13660
41 + 13619 = 13660
47 + 13613 = 13660
83 + 13577 = 13660
107 + 13553 = 13660
137 + 13523 = 13660
173 + 13487 = 13660
191 + 13469 = 13660

Showing the first eight; more decompositions exist.
