Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616420, here are decompositions:

13 + 8616407 = 8616420
23 + 8616397 = 8616420
41 + 8616379 = 8616420
47 + 8616373 = 8616420
67 + 8616353 = 8616420
83 + 8616337 = 8616420
97 + 8616323 = 8616420
101 + 8616319 = 8616420

Showing the first eight; more decompositions exist.
