Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648020, here are decompositions:

23 + 8647997 = 8648020
41 + 8647979 = 8648020
53 + 8647967 = 8648020
71 + 8647949 = 8648020
83 + 8647937 = 8648020
107 + 8647913 = 8648020
131 + 8647889 = 8648020
197 + 8647823 = 8648020

Showing the first eight; more decompositions exist.
