Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648866, here are decompositions:

3 + 8648863 = 8648866
29 + 8648837 = 8648866
53 + 8648813 = 8648866
137 + 8648729 = 8648866
179 + 8648687 = 8648866
353 + 8648513 = 8648866
419 + 8648447 = 8648866
599 + 8648267 = 8648866

Showing the first eight; more decompositions exist.
