Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658558, here are decompositions:

5 + 8658553 = 8658558
31 + 8658527 = 8658558
89 + 8658469 = 8658558
127 + 8658431 = 8658558
229 + 8658329 = 8658558
269 + 8658289 = 8658558
281 + 8658277 = 8658558
397 + 8658161 = 8658558

Showing the first eight; more decompositions exist.
