Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648480, here are decompositions:

67 + 8648413 = 8648480
109 + 8648371 = 8648480
157 + 8648323 = 8648480
163 + 8648317 = 8648480
229 + 8648251 = 8648480
241 + 8648239 = 8648480
331 + 8648149 = 8648480
349 + 8648131 = 8648480

Showing the first eight; more decompositions exist.
