Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665824, here are decompositions:

7 + 8665817 = 8665824
47 + 8665777 = 8665824
107 + 8665717 = 8665824
157 + 8665667 = 8665824
173 + 8665651 = 8665824
191 + 8665633 = 8665824
241 + 8665583 = 8665824
257 + 8665567 = 8665824

Showing the first eight; more decompositions exist.
