Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620380, here are decompositions:

11 + 8620369 = 8620380
19 + 8620361 = 8620380
31 + 8620349 = 8620380
53 + 8620327 = 8620380
73 + 8620307 = 8620380
103 + 8620277 = 8620380
113 + 8620267 = 8620380
149 + 8620231 = 8620380

Showing the first eight; more decompositions exist.
