Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644506, here are decompositions:

5 + 8644501 = 8644506
7 + 8644499 = 8644506
29 + 8644477 = 8644506
53 + 8644453 = 8644506
67 + 8644439 = 8644506
109 + 8644397 = 8644506
179 + 8644327 = 8644506
263 + 8644243 = 8644506

Showing the first eight; more decompositions exist.
