Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646518, here are decompositions:

7 + 8646511 = 8646518
31 + 8646487 = 8646518
61 + 8646457 = 8646518
157 + 8646361 = 8646518
241 + 8646277 = 8646518
271 + 8646247 = 8646518
337 + 8646181 = 8646518
457 + 8646061 = 8646518

Showing the first eight; more decompositions exist.
