Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658424, here are decompositions:

11 + 8658413 = 8658424
41 + 8658383 = 8658424
53 + 8658371 = 8658424
101 + 8658323 = 8658424
191 + 8658233 = 8658424
263 + 8658161 = 8658424
317 + 8658107 = 8658424
491 + 8657933 = 8658424

Showing the first eight; more decompositions exist.
