Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680724, here are decompositions:

7 + 8680717 = 8680724
181 + 8680543 = 8680724
211 + 8680513 = 8680724
223 + 8680501 = 8680724
307 + 8680417 = 8680724
397 + 8680327 = 8680724
421 + 8680303 = 8680724
457 + 8680267 = 8680724

Showing the first eight; more decompositions exist.
