Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645510, here are decompositions:

19 + 8645491 = 8645510
61 + 8645449 = 8645510
67 + 8645443 = 8645510
79 + 8645431 = 8645510
103 + 8645407 = 8645510
151 + 8645359 = 8645510
157 + 8645353 = 8645510
229 + 8645281 = 8645510

Showing the first eight; more decompositions exist.
