Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648764, here are decompositions:

17 + 8648747 = 8648764
23 + 8648741 = 8648764
227 + 8648537 = 8648764
233 + 8648531 = 8648764
251 + 8648513 = 8648764
263 + 8648501 = 8648764
317 + 8648447 = 8648764
431 + 8648333 = 8648764

Showing the first eight; more decompositions exist.
