Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648468, here are decompositions:

79 + 8648389 = 8648468
97 + 8648371 = 8648468
151 + 8648317 = 8648468
229 + 8648239 = 8648468
277 + 8648191 = 8648468
337 + 8648131 = 8648468
541 + 8647927 = 8648468
571 + 8647897 = 8648468

Showing the first eight; more decompositions exist.
