Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640002, here are decompositions:

79 + 8639923 = 8640002
103 + 8639899 = 8640002
139 + 8639863 = 8640002
193 + 8639809 = 8640002
199 + 8639803 = 8640002
223 + 8639779 = 8640002
229 + 8639773 = 8640002
439 + 8639563 = 8640002

Showing the first eight; more decompositions exist.
