Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644524, here are decompositions:

13 + 8644511 = 8644524
17 + 8644507 = 8644524
23 + 8644501 = 8644524
47 + 8644477 = 8644524
67 + 8644457 = 8644524
71 + 8644453 = 8644524
73 + 8644451 = 8644524
127 + 8644397 = 8644524

Showing the first eight; more decompositions exist.
