Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620488, here are decompositions:

59 + 8620429 = 8620488
127 + 8620361 = 8620488
139 + 8620349 = 8620488
181 + 8620307 = 8620488
199 + 8620289 = 8620488
211 + 8620277 = 8620488
229 + 8620259 = 8620488
257 + 8620231 = 8620488

Showing the first eight; more decompositions exist.
