Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616386, here are decompositions:

7 + 8616379 = 8616386
13 + 8616373 = 8616386
67 + 8616319 = 8616386
139 + 8616247 = 8616386
199 + 8616187 = 8616386
349 + 8616037 = 8616386
367 + 8616019 = 8616386
397 + 8615989 = 8616386

Showing the first eight; more decompositions exist.
