Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620386, here are decompositions:

17 + 8620369 = 8620386
37 + 8620349 = 8620386
59 + 8620327 = 8620386
79 + 8620307 = 8620386
97 + 8620289 = 8620386
109 + 8620277 = 8620386
127 + 8620259 = 8620386
167 + 8620219 = 8620386

Showing the first eight; more decompositions exist.
