Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641416, here are decompositions:

67 + 8641349 = 8641416
89 + 8641327 = 8641416
97 + 8641319 = 8641416
107 + 8641309 = 8641416
127 + 8641289 = 8641416
167 + 8641249 = 8641416
229 + 8641187 = 8641416
269 + 8641147 = 8641416

Showing the first eight; more decompositions exist.
