Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646516, here are decompositions:

5 + 8646511 = 8646516
13 + 8646503 = 8646516
19 + 8646497 = 8646516
29 + 8646487 = 8646516
37 + 8646479 = 8646516
59 + 8646457 = 8646516
113 + 8646403 = 8646516
127 + 8646389 = 8646516

Showing the first eight; more decompositions exist.
