Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8480, here are decompositions:

13 + 8467 = 8480
19 + 8461 = 8480
37 + 8443 = 8480
61 + 8419 = 8480
103 + 8377 = 8480
127 + 8353 = 8480
151 + 8329 = 8480
163 + 8317 = 8480

Showing the first eight; more decompositions exist.
