Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640132, here are decompositions:

23 + 8640109 = 8640132
73 + 8640059 = 8640132
131 + 8640001 = 8640132
181 + 8639951 = 8640132
211 + 8639921 = 8640132
223 + 8639909 = 8640132
229 + 8639903 = 8640132
233 + 8639899 = 8640132

Showing the first eight; more decompositions exist.
