Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641262, here are decompositions:

13 + 8641249 = 8641262
31 + 8641231 = 8641262
199 + 8641063 = 8641262
313 + 8640949 = 8641262
373 + 8640889 = 8641262
379 + 8640883 = 8641262
439 + 8640823 = 8641262
463 + 8640799 = 8641262

Showing the first eight; more decompositions exist.
