Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648772, here are decompositions:

23 + 8648749 = 8648772
31 + 8648741 = 8648772
43 + 8648729 = 8648772
71 + 8648701 = 8648772
229 + 8648543 = 8648772
239 + 8648533 = 8648772
241 + 8648531 = 8648772
271 + 8648501 = 8648772

Showing the first eight; more decompositions exist.
