Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668824, here are decompositions:

7 + 8668817 = 8668824
11 + 8668813 = 8668824
23 + 8668801 = 8668824
41 + 8668783 = 8668824
61 + 8668763 = 8668824
83 + 8668741 = 8668824
103 + 8668721 = 8668824
113 + 8668711 = 8668824

Showing the first eight; more decompositions exist.
