Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648678, here are decompositions:

127 + 8648551 = 8648678
307 + 8648371 = 8648678
331 + 8648347 = 8648678
439 + 8648239 = 8648678
457 + 8648221 = 8648678
487 + 8648191 = 8648678
499 + 8648179 = 8648678
547 + 8648131 = 8648678

Showing the first eight; more decompositions exist.
