Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19474, here are decompositions:

3 + 19471 = 19474
5 + 19469 = 19474
11 + 19463 = 19474
17 + 19457 = 19474
41 + 19433 = 19474
47 + 19427 = 19474
53 + 19421 = 19474
71 + 19403 = 19474

Showing the first eight; more decompositions exist.
