Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648808, here are decompositions:

11 + 8648797 = 8648808
17 + 8648791 = 8648808
29 + 8648779 = 8648808
59 + 8648749 = 8648808
61 + 8648747 = 8648808
67 + 8648741 = 8648808
71 + 8648737 = 8648808
79 + 8648729 = 8648808

Showing the first eight; more decompositions exist.
