Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658418, here are decompositions:

5 + 8658413 = 8658418
47 + 8658371 = 8658418
89 + 8658329 = 8658418
257 + 8658161 = 8658418
281 + 8658137 = 8658418
311 + 8658107 = 8658418
317 + 8658101 = 8658418
359 + 8658059 = 8658418

Showing the first eight; more decompositions exist.
