Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616398, here are decompositions:

19 + 8616379 = 8616398
61 + 8616337 = 8616398
79 + 8616319 = 8616398
127 + 8616271 = 8616398
151 + 8616247 = 8616398
157 + 8616241 = 8616398
181 + 8616217 = 8616398
199 + 8616199 = 8616398

Showing the first eight; more decompositions exist.
