Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680210, here are decompositions:

23 + 8680187 = 8680210
53 + 8680157 = 8680210
89 + 8680121 = 8680210
107 + 8680103 = 8680210
137 + 8680073 = 8680210
167 + 8680043 = 8680210
173 + 8680037 = 8680210
239 + 8679971 = 8680210

Showing the first eight; more decompositions exist.
