Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648518, here are decompositions:

5 + 8648513 = 8648518
17 + 8648501 = 8648518
59 + 8648459 = 8648518
71 + 8648447 = 8648518
149 + 8648369 = 8648518
251 + 8648267 = 8648518
419 + 8648099 = 8648518
521 + 8647997 = 8648518

Showing the first eight; more decompositions exist.
