Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645504, here are decompositions:

13 + 8645491 = 8645504
61 + 8645443 = 8645504
73 + 8645431 = 8645504
97 + 8645407 = 8645504
151 + 8645353 = 8645504
163 + 8645341 = 8645504
211 + 8645293 = 8645504
223 + 8645281 = 8645504

Showing the first eight; more decompositions exist.
