Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658624, here are decompositions:

5 + 8658619 = 8658624
11 + 8658613 = 8658624
41 + 8658583 = 8658624
43 + 8658581 = 8658624
47 + 8658577 = 8658624
53 + 8658571 = 8658624
71 + 8658553 = 8658624
97 + 8658527 = 8658624

Showing the first eight; more decompositions exist.
