Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640010, here are decompositions:

23 + 8639987 = 8640010
59 + 8639951 = 8640010
89 + 8639921 = 8640010
101 + 8639909 = 8640010
107 + 8639903 = 8640010
173 + 8639837 = 8640010
191 + 8639819 = 8640010
257 + 8639753 = 8640010

Showing the first eight; more decompositions exist.
