Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620470, here are decompositions:

41 + 8620429 = 8620470
101 + 8620369 = 8620470
109 + 8620361 = 8620470
163 + 8620307 = 8620470
181 + 8620289 = 8620470
193 + 8620277 = 8620470
211 + 8620259 = 8620470
239 + 8620231 = 8620470

Showing the first eight; more decompositions exist.
