Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640084, here are decompositions:

67 + 8640017 = 8640084
71 + 8640013 = 8640084
83 + 8640001 = 8640084
97 + 8639987 = 8640084
107 + 8639977 = 8640084
163 + 8639921 = 8640084
181 + 8639903 = 8640084
281 + 8639803 = 8640084

Showing the first eight; more decompositions exist.
