Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680800, here are decompositions:

19 + 8680781 = 8680800
31 + 8680769 = 8680800
47 + 8680753 = 8680800
59 + 8680741 = 8680800
67 + 8680733 = 8680800
83 + 8680717 = 8680800
101 + 8680699 = 8680800
103 + 8680697 = 8680800

Showing the first eight; more decompositions exist.
