Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648478, here are decompositions:

19 + 8648459 = 8648478
31 + 8648447 = 8648478
89 + 8648389 = 8648478
107 + 8648371 = 8648478
109 + 8648369 = 8648478
131 + 8648347 = 8648478
211 + 8648267 = 8648478
227 + 8648251 = 8648478

Showing the first eight; more decompositions exist.
