Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646508, here are decompositions:

5 + 8646503 = 8646508
11 + 8646497 = 8646508
29 + 8646479 = 8646508
107 + 8646401 = 8646508
131 + 8646377 = 8646508
179 + 8646329 = 8646508
191 + 8646317 = 8646508
239 + 8646269 = 8646508

Showing the first eight; more decompositions exist.
