Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640006, here are decompositions:

5 + 8640001 = 8640006
19 + 8639987 = 8640006
29 + 8639977 = 8640006
83 + 8639923 = 8640006
97 + 8639909 = 8640006
103 + 8639903 = 8640006
107 + 8639899 = 8640006
157 + 8639849 = 8640006

Showing the first eight; more decompositions exist.
