Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680720, here are decompositions:

3 + 8680717 = 8680720
23 + 8680697 = 8680720
29 + 8680691 = 8680720
89 + 8680631 = 8680720
101 + 8680619 = 8680720
107 + 8680613 = 8680720
137 + 8680583 = 8680720
239 + 8680481 = 8680720

Showing the first eight; more decompositions exist.
