Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640024, here are decompositions:

7 + 8640017 = 8640024
11 + 8640013 = 8640024
23 + 8640001 = 8640024
37 + 8639987 = 8640024
47 + 8639977 = 8640024
73 + 8639951 = 8640024
101 + 8639923 = 8640024
103 + 8639921 = 8640024

Showing the first eight; more decompositions exist.
