Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680878, here are decompositions:

7 + 8680871 = 8680878
67 + 8680811 = 8680878
97 + 8680781 = 8680878
109 + 8680769 = 8680878
137 + 8680741 = 8680878
179 + 8680699 = 8680878
181 + 8680697 = 8680878
277 + 8680601 = 8680878

Showing the first eight; more decompositions exist.
