Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680440, here are decompositions:

23 + 8680417 = 8680440
31 + 8680409 = 8680440
61 + 8680379 = 8680440
71 + 8680369 = 8680440
103 + 8680337 = 8680440
113 + 8680327 = 8680440
127 + 8680313 = 8680440
137 + 8680303 = 8680440

Showing the first eight; more decompositions exist.
