Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648474, here are decompositions:

61 + 8648413 = 8648474
103 + 8648371 = 8648474
127 + 8648347 = 8648474
151 + 8648323 = 8648474
157 + 8648317 = 8648474
223 + 8648251 = 8648474
283 + 8648191 = 8648474
547 + 8647927 = 8648474

Showing the first eight; more decompositions exist.
