Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616618, here are decompositions:

19 + 8616599 = 8616618
71 + 8616547 = 8616618
211 + 8616407 = 8616618
239 + 8616379 = 8616618
281 + 8616337 = 8616618
337 + 8616281 = 8616618
347 + 8616271 = 8616618
397 + 8616221 = 8616618

Showing the first eight; more decompositions exist.
