Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680828, here are decompositions:

5 + 8680823 = 8680828
17 + 8680811 = 8680828
47 + 8680781 = 8680828
59 + 8680769 = 8680828
131 + 8680697 = 8680828
137 + 8680691 = 8680828
197 + 8680631 = 8680828
227 + 8680601 = 8680828

Showing the first eight; more decompositions exist.
