Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680770, here are decompositions:

17 + 8680753 = 8680770
29 + 8680741 = 8680770
37 + 8680733 = 8680770
47 + 8680723 = 8680770
53 + 8680717 = 8680770
71 + 8680699 = 8680770
73 + 8680697 = 8680770
79 + 8680691 = 8680770

Showing the first eight; more decompositions exist.
