Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8474, here are decompositions:

7 + 8467 = 8474
13 + 8461 = 8474
31 + 8443 = 8474
43 + 8431 = 8474
97 + 8377 = 8474
157 + 8317 = 8474
163 + 8311 = 8474
181 + 8293 = 8474

Showing the first eight; more decompositions exist.
