Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620392, here are decompositions:

23 + 8620369 = 8620392
31 + 8620361 = 8620392
43 + 8620349 = 8620392
103 + 8620289 = 8620392
173 + 8620219 = 8620392
181 + 8620211 = 8620392
233 + 8620159 = 8620392
241 + 8620151 = 8620392

Showing the first eight; more decompositions exist.
