Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620320, here are decompositions:

13 + 8620307 = 8620320
31 + 8620289 = 8620320
43 + 8620277 = 8620320
53 + 8620267 = 8620320
61 + 8620259 = 8620320
89 + 8620231 = 8620320
101 + 8620219 = 8620320
103 + 8620217 = 8620320

Showing the first eight; more decompositions exist.
