Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680900, here are decompositions:

29 + 8680871 = 8680900
89 + 8680811 = 8680900
131 + 8680769 = 8680900
167 + 8680733 = 8680900
269 + 8680631 = 8680900
281 + 8680619 = 8680900
317 + 8680583 = 8680900
419 + 8680481 = 8680900

Showing the first eight; more decompositions exist.
