Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620558, here are decompositions:

5 + 8620553 = 8620558
29 + 8620529 = 8620558
59 + 8620499 = 8620558
197 + 8620361 = 8620558
251 + 8620307 = 8620558
269 + 8620289 = 8620558
281 + 8620277 = 8620558
347 + 8620211 = 8620558

Showing the first eight; more decompositions exist.
