Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616518, here are decompositions:

19 + 8616499 = 8616518
61 + 8616457 = 8616518
139 + 8616379 = 8616518
181 + 8616337 = 8616518
199 + 8616319 = 8616518
271 + 8616247 = 8616518
277 + 8616241 = 8616518
331 + 8616187 = 8616518

Showing the first eight; more decompositions exist.
