Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620458, here are decompositions:

29 + 8620429 = 8620458
89 + 8620369 = 8620458
97 + 8620361 = 8620458
109 + 8620349 = 8620458
131 + 8620327 = 8620458
151 + 8620307 = 8620458
181 + 8620277 = 8620458
191 + 8620267 = 8620458

Showing the first eight; more decompositions exist.
