Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617216, here are decompositions:

5 + 8617211 = 8617216
29 + 8617187 = 8617216
107 + 8617109 = 8617216
227 + 8616989 = 8617216
269 + 8616947 = 8617216
347 + 8616869 = 8617216
383 + 8616833 = 8617216
389 + 8616827 = 8617216

Showing the first eight; more decompositions exist.
