Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645558, here are decompositions:

67 + 8645491 = 8645558
109 + 8645449 = 8645558
127 + 8645431 = 8645558
151 + 8645407 = 8645558
199 + 8645359 = 8645558
277 + 8645281 = 8645558
379 + 8645179 = 8645558
487 + 8645071 = 8645558

Showing the first eight; more decompositions exist.
