Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644004, here are decompositions:

7 + 8643997 = 8644004
13 + 8643991 = 8644004
283 + 8643721 = 8644004
307 + 8643697 = 8644004
331 + 8643673 = 8644004
373 + 8643631 = 8644004
547 + 8643457 = 8644004
571 + 8643433 = 8644004

Showing the first eight; more decompositions exist.
