Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15474, here are decompositions:

7 + 15467 = 15474
13 + 15461 = 15474
23 + 15451 = 15474
31 + 15443 = 15474
47 + 15427 = 15474
61 + 15413 = 15474
73 + 15401 = 15474
83 + 15391 = 15474

Showing the first eight; more decompositions exist.
