Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644988, here are decompositions:

31 + 8644957 = 8644988
61 + 8644927 = 8644988
127 + 8644861 = 8644988
337 + 8644651 = 8644988
379 + 8644609 = 8644988
487 + 8644501 = 8644988
661 + 8644327 = 8644988
727 + 8644261 = 8644988

Showing the first eight; more decompositions exist.
