Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642480, here are decompositions:

13 + 8642467 = 8642480
31 + 8642449 = 8642480
97 + 8642383 = 8642480
151 + 8642329 = 8642480
199 + 8642281 = 8642480
283 + 8642197 = 8642480
307 + 8642173 = 8642480
373 + 8642107 = 8642480

Showing the first eight; more decompositions exist.
