Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640768, here are decompositions:

7 + 8640761 = 8640768
29 + 8640739 = 8640768
61 + 8640707 = 8640768
67 + 8640701 = 8640768
79 + 8640689 = 8640768
89 + 8640679 = 8640768
167 + 8640601 = 8640768
181 + 8640587 = 8640768

Showing the first eight; more decompositions exist.
