Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641216, here are decompositions:

5 + 8641211 = 8641216
29 + 8641187 = 8641216
83 + 8641133 = 8641216
137 + 8641079 = 8641216
239 + 8640977 = 8641216
449 + 8640767 = 8641216
503 + 8640713 = 8641216
509 + 8640707 = 8641216

Showing the first eight; more decompositions exist.
