Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680960, here are decompositions:

53 + 8680907 = 8680960
59 + 8680901 = 8680960
89 + 8680871 = 8680960
137 + 8680823 = 8680960
149 + 8680811 = 8680960
179 + 8680781 = 8680960
191 + 8680769 = 8680960
227 + 8680733 = 8680960

Showing the first eight; more decompositions exist.
