Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648766, here are decompositions:

17 + 8648749 = 8648766
19 + 8648747 = 8648766
29 + 8648737 = 8648766
37 + 8648729 = 8648766
79 + 8648687 = 8648766
89 + 8648677 = 8648766
223 + 8648543 = 8648766
229 + 8648537 = 8648766

Showing the first eight; more decompositions exist.
