Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683440, here are decompositions:

13 + 8683427 = 8683440
47 + 8683393 = 8683440
109 + 8683331 = 8683440
113 + 8683327 = 8683440
131 + 8683309 = 8683440
137 + 8683303 = 8683440
179 + 8683261 = 8683440
191 + 8683249 = 8683440

Showing the first eight; more decompositions exist.
