Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640026, here are decompositions:

13 + 8640013 = 8640026
103 + 8639923 = 8640026
127 + 8639899 = 8640026
163 + 8639863 = 8640026
223 + 8639803 = 8640026
229 + 8639797 = 8640026
277 + 8639749 = 8640026
313 + 8639713 = 8640026

Showing the first eight; more decompositions exist.
