Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683278, here are decompositions:

17 + 8683261 = 8683278
29 + 8683249 = 8683278
41 + 8683237 = 8683278
47 + 8683231 = 8683278
59 + 8683219 = 8683278
61 + 8683217 = 8683278
89 + 8683189 = 8683278
181 + 8683097 = 8683278

Showing the first eight; more decompositions exist.
