Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644518, here are decompositions:

7 + 8644511 = 8644518
11 + 8644507 = 8644518
17 + 8644501 = 8644518
19 + 8644499 = 8644518
41 + 8644477 = 8644518
61 + 8644457 = 8644518
67 + 8644451 = 8644518
79 + 8644439 = 8644518

Showing the first eight; more decompositions exist.
