Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680978, here are decompositions:

71 + 8680907 = 8680978
107 + 8680871 = 8680978
167 + 8680811 = 8680978
197 + 8680781 = 8680978
281 + 8680697 = 8680978
347 + 8680631 = 8680978
359 + 8680619 = 8680978
419 + 8680559 = 8680978

Showing the first eight; more decompositions exist.
