Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641484, here are decompositions:

13 + 8641471 = 8641484
31 + 8641453 = 8641484
157 + 8641327 = 8641484
211 + 8641273 = 8641484
337 + 8641147 = 8641484
421 + 8641063 = 8641484
601 + 8640883 = 8641484
613 + 8640871 = 8641484

Showing the first eight; more decompositions exist.
