Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640012, here are decompositions:

11 + 8640001 = 8640012
61 + 8639951 = 8640012
89 + 8639923 = 8640012
103 + 8639909 = 8640012
109 + 8639903 = 8640012
113 + 8639899 = 8640012
149 + 8639863 = 8640012
163 + 8639849 = 8640012

Showing the first eight; more decompositions exist.
