Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620374, here are decompositions:

5 + 8620369 = 8620374
13 + 8620361 = 8620374
47 + 8620327 = 8620374
67 + 8620307 = 8620374
97 + 8620277 = 8620374
107 + 8620267 = 8620374
157 + 8620217 = 8620374
163 + 8620211 = 8620374

Showing the first eight; more decompositions exist.
