Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18474, here are decompositions:

13 + 18461 = 18474
17 + 18457 = 18474
23 + 18451 = 18474
31 + 18443 = 18474
41 + 18433 = 18474
47 + 18427 = 18474
61 + 18413 = 18474
73 + 18401 = 18474

Showing the first eight; more decompositions exist.
