Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648418, here are decompositions:

5 + 8648413 = 8648418
29 + 8648389 = 8648418
47 + 8648371 = 8648418
71 + 8648347 = 8648418
101 + 8648317 = 8648418
151 + 8648267 = 8648418
167 + 8648251 = 8648418
179 + 8648239 = 8648418

Showing the first eight; more decompositions exist.
