Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682440, here are decompositions:

3 + 8682437 = 8682440
7 + 8682433 = 8682440
31 + 8682409 = 8682440
37 + 8682403 = 8682440
97 + 8682343 = 8682440
163 + 8682277 = 8682440
199 + 8682241 = 8682440
211 + 8682229 = 8682440

Showing the first eight; more decompositions exist.
