Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680784, here are decompositions:

3 + 8680781 = 8680784
31 + 8680753 = 8680784
43 + 8680741 = 8680784
61 + 8680723 = 8680784
67 + 8680717 = 8680784
241 + 8680543 = 8680784
271 + 8680513 = 8680784
283 + 8680501 = 8680784

Showing the first eight; more decompositions exist.
