Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620422, here are decompositions:

29 + 8620393 = 8620422
53 + 8620369 = 8620422
61 + 8620361 = 8620422
73 + 8620349 = 8620422
163 + 8620259 = 8620422
191 + 8620231 = 8620422
211 + 8620211 = 8620422
233 + 8620189 = 8620422

Showing the first eight; more decompositions exist.
