Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640166, here are decompositions:

5 + 8640161 = 8640166
107 + 8640059 = 8640166
149 + 8640017 = 8640166
179 + 8639987 = 8640166
257 + 8639909 = 8640166
263 + 8639903 = 8640166
317 + 8639849 = 8640166
347 + 8639819 = 8640166

Showing the first eight; more decompositions exist.
