Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644010, here are decompositions:

13 + 8643997 = 8644010
19 + 8643991 = 8644010
223 + 8643787 = 8644010
313 + 8643697 = 8644010
337 + 8643673 = 8644010
379 + 8643631 = 8644010
421 + 8643589 = 8644010
433 + 8643577 = 8644010

Showing the first eight; more decompositions exist.
