Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17538, here are decompositions:

19 + 17519 = 17538
29 + 17509 = 17538
41 + 17497 = 17538
47 + 17491 = 17538
61 + 17477 = 17538
67 + 17471 = 17538
71 + 17467 = 17538
89 + 17449 = 17538

Showing the first eight; more decompositions exist.
