Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640804, here are decompositions:

5 + 8640799 = 8640804
17 + 8640787 = 8640804
23 + 8640781 = 8640804
37 + 8640767 = 8640804
43 + 8640761 = 8640804
71 + 8640733 = 8640804
97 + 8640707 = 8640804
101 + 8640703 = 8640804

Showing the first eight; more decompositions exist.
