Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648558, here are decompositions:

7 + 8648551 = 8648558
211 + 8648347 = 8648558
241 + 8648317 = 8648558
307 + 8648251 = 8648558
337 + 8648221 = 8648558
367 + 8648191 = 8648558
379 + 8648179 = 8648558
409 + 8648149 = 8648558

Showing the first eight; more decompositions exist.
