Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643804, here are decompositions:

7 + 8643797 = 8643804
17 + 8643787 = 8643804
47 + 8643757 = 8643804
83 + 8643721 = 8643804
97 + 8643707 = 8643804
107 + 8643697 = 8643804
131 + 8643673 = 8643804
157 + 8643647 = 8643804

Showing the first eight; more decompositions exist.
