Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680780, here are decompositions:

11 + 8680769 = 8680780
47 + 8680733 = 8680780
83 + 8680697 = 8680780
89 + 8680691 = 8680780
149 + 8680631 = 8680780
167 + 8680613 = 8680780
179 + 8680601 = 8680780
197 + 8680583 = 8680780

Showing the first eight; more decompositions exist.
