Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648736, here are decompositions:

7 + 8648729 = 8648736
59 + 8648677 = 8648736
179 + 8648557 = 8648736
193 + 8648543 = 8648736
199 + 8648537 = 8648736
223 + 8648513 = 8648736
277 + 8648459 = 8648736
347 + 8648389 = 8648736

Showing the first eight; more decompositions exist.
