Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683240, here are decompositions:

3 + 8683237 = 8683240
17 + 8683223 = 8683240
23 + 8683217 = 8683240
53 + 8683187 = 8683240
149 + 8683091 = 8683240
179 + 8683061 = 8683240
227 + 8683013 = 8683240
239 + 8683001 = 8683240

Showing the first eight; more decompositions exist.
