Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620506, here are decompositions:

7 + 8620499 = 8620506
113 + 8620393 = 8620506
137 + 8620369 = 8620506
157 + 8620349 = 8620506
179 + 8620327 = 8620506
199 + 8620307 = 8620506
229 + 8620277 = 8620506
239 + 8620267 = 8620506

Showing the first eight; more decompositions exist.
