Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620528, here are decompositions:

29 + 8620499 = 8620528
167 + 8620361 = 8620528
179 + 8620349 = 8620528
239 + 8620289 = 8620528
251 + 8620277 = 8620528
269 + 8620259 = 8620528
311 + 8620217 = 8620528
317 + 8620211 = 8620528

Showing the first eight; more decompositions exist.
