Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620338, here are decompositions:

11 + 8620327 = 8620338
31 + 8620307 = 8620338
61 + 8620277 = 8620338
71 + 8620267 = 8620338
79 + 8620259 = 8620338
107 + 8620231 = 8620338
127 + 8620211 = 8620338
149 + 8620189 = 8620338

Showing the first eight; more decompositions exist.
