Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645480, here are decompositions:

3 + 8645477 = 8645480
31 + 8645449 = 8645480
37 + 8645443 = 8645480
73 + 8645407 = 8645480
127 + 8645353 = 8645480
139 + 8645341 = 8645480
199 + 8645281 = 8645480
211 + 8645269 = 8645480

Showing the first eight; more decompositions exist.
