Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16540, here are decompositions:

11 + 16529 = 16540
47 + 16493 = 16540
53 + 16487 = 16540
59 + 16481 = 16540
89 + 16451 = 16540
107 + 16433 = 16540
113 + 16427 = 16540
179 + 16361 = 16540

Showing the first eight; more decompositions exist.
