Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641286, here are decompositions:

13 + 8641273 = 8641286
37 + 8641249 = 8641286
139 + 8641147 = 8641286
193 + 8641093 = 8641286
223 + 8641063 = 8641286
337 + 8640949 = 8641286
397 + 8640889 = 8641286
463 + 8640823 = 8641286

Showing the first eight; more decompositions exist.
