Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658340, here are decompositions:

11 + 8658329 = 8658340
17 + 8658323 = 8658340
107 + 8658233 = 8658340
137 + 8658203 = 8658340
179 + 8658161 = 8658340
233 + 8658107 = 8658340
239 + 8658101 = 8658340
281 + 8658059 = 8658340

Showing the first eight; more decompositions exist.
