Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646782, here are decompositions:

3 + 8646779 = 8646782
31 + 8646751 = 8646782
61 + 8646721 = 8646782
73 + 8646709 = 8646782
211 + 8646571 = 8646782
223 + 8646559 = 8646782
271 + 8646511 = 8646782
379 + 8646403 = 8646782

Showing the first eight; more decompositions exist.
