Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648424, here are decompositions:

11 + 8648413 = 8648424
53 + 8648371 = 8648424
101 + 8648323 = 8648424
107 + 8648317 = 8648424
157 + 8648267 = 8648424
173 + 8648251 = 8648424
233 + 8648191 = 8648424
293 + 8648131 = 8648424

Showing the first eight; more decompositions exist.
