Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680840, here are decompositions:

17 + 8680823 = 8680840
29 + 8680811 = 8680840
59 + 8680781 = 8680840
71 + 8680769 = 8680840
107 + 8680733 = 8680840
149 + 8680691 = 8680840
227 + 8680613 = 8680840
239 + 8680601 = 8680840

Showing the first eight; more decompositions exist.
