Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648402, here are decompositions:

13 + 8648389 = 8648402
31 + 8648371 = 8648402
79 + 8648323 = 8648402
151 + 8648251 = 8648402
163 + 8648239 = 8648402
181 + 8648221 = 8648402
211 + 8648191 = 8648402
223 + 8648179 = 8648402

Showing the first eight; more decompositions exist.
