Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42474, here are decompositions:

7 + 42467 = 42474
11 + 42463 = 42474
13 + 42461 = 42474
17 + 42457 = 42474
23 + 42451 = 42474
31 + 42443 = 42474
37 + 42437 = 42474
41 + 42433 = 42474

Showing the first eight; more decompositions exist.
