Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648280, here are decompositions:

13 + 8648267 = 8648280
29 + 8648251 = 8648280
41 + 8648239 = 8648280
59 + 8648221 = 8648280
89 + 8648191 = 8648280
101 + 8648179 = 8648280
131 + 8648149 = 8648280
149 + 8648131 = 8648280

Showing the first eight; more decompositions exist.
