Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686518, here are decompositions:

17 + 8686501 = 8686518
19 + 8686499 = 8686518
31 + 8686487 = 8686518
47 + 8686471 = 8686518
59 + 8686459 = 8686518
97 + 8686421 = 8686518
109 + 8686409 = 8686518
149 + 8686369 = 8686518

Showing the first eight; more decompositions exist.
