Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640016, here are decompositions:

3 + 8640013 = 8640016
29 + 8639987 = 8640016
107 + 8639909 = 8640016
113 + 8639903 = 8640016
167 + 8639849 = 8640016
179 + 8639837 = 8640016
197 + 8639819 = 8640016
263 + 8639753 = 8640016

Showing the first eight; more decompositions exist.
