Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640048, here are decompositions:

31 + 8640017 = 8640048
47 + 8640001 = 8640048
61 + 8639987 = 8640048
71 + 8639977 = 8640048
97 + 8639951 = 8640048
127 + 8639921 = 8640048
139 + 8639909 = 8640048
149 + 8639899 = 8640048

Showing the first eight; more decompositions exist.
