Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680748, here are decompositions:

7 + 8680741 = 8680748
31 + 8680717 = 8680748
79 + 8680669 = 8680748
277 + 8680471 = 8680748
331 + 8680417 = 8680748
379 + 8680369 = 8680748
421 + 8680327 = 8680748
499 + 8680249 = 8680748

Showing the first eight; more decompositions exist.
