Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641418, here are decompositions:

67 + 8641351 = 8641418
109 + 8641309 = 8641418
271 + 8641147 = 8641418
547 + 8640871 = 8641418
601 + 8640817 = 8641418
619 + 8640799 = 8641418
631 + 8640787 = 8641418
727 + 8640691 = 8641418

Showing the first eight; more decompositions exist.
