Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648208, here are decompositions:

17 + 8648191 = 8648208
29 + 8648179 = 8648208
59 + 8648149 = 8648208
97 + 8648111 = 8648208
109 + 8648099 = 8648208
211 + 8647997 = 8648208
229 + 8647979 = 8648208
241 + 8647967 = 8648208

Showing the first eight; more decompositions exist.
