Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620378, here are decompositions:

17 + 8620361 = 8620378
29 + 8620349 = 8620378
71 + 8620307 = 8620378
89 + 8620289 = 8620378
101 + 8620277 = 8620378
167 + 8620211 = 8620378
191 + 8620187 = 8620378
227 + 8620151 = 8620378

Showing the first eight; more decompositions exist.
