Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620550, here are decompositions:

7 + 8620543 = 8620550
157 + 8620393 = 8620550
181 + 8620369 = 8620550
223 + 8620327 = 8620550
283 + 8620267 = 8620550
331 + 8620219 = 8620550
409 + 8620141 = 8620550
439 + 8620111 = 8620550

Showing the first eight; more decompositions exist.
