Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620512, here are decompositions:

13 + 8620499 = 8620512
83 + 8620429 = 8620512
151 + 8620361 = 8620512
163 + 8620349 = 8620512
223 + 8620289 = 8620512
281 + 8620231 = 8620512
293 + 8620219 = 8620512
353 + 8620159 = 8620512

Showing the first eight; more decompositions exist.
