Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648166, here are decompositions:

17 + 8648149 = 8648166
53 + 8648113 = 8648166
67 + 8648099 = 8648166
73 + 8648093 = 8648166
83 + 8648083 = 8648166
173 + 8647993 = 8648166
199 + 8647967 = 8648166
229 + 8647937 = 8648166

Showing the first eight; more decompositions exist.
