Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648836, here are decompositions:

3 + 8648833 = 8648836
5 + 8648831 = 8648836
23 + 8648813 = 8648836
89 + 8648747 = 8648836
107 + 8648729 = 8648836
149 + 8648687 = 8648836
293 + 8648543 = 8648836
389 + 8648447 = 8648836

Showing the first eight; more decompositions exist.
