Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680824, here are decompositions:

11 + 8680813 = 8680824
13 + 8680811 = 8680824
23 + 8680801 = 8680824
43 + 8680781 = 8680824
71 + 8680753 = 8680824
83 + 8680741 = 8680824
101 + 8680723 = 8680824
107 + 8680717 = 8680824

Showing the first eight; more decompositions exist.
