Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683786, here are decompositions:

3 + 8683783 = 8683786
5 + 8683781 = 8683786
17 + 8683769 = 8683786
29 + 8683757 = 8683786
149 + 8683637 = 8683786
173 + 8683613 = 8683786
179 + 8683607 = 8683786
233 + 8683553 = 8683786

Showing the first eight; more decompositions exist.
