Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670558, here are decompositions:

5 + 8670553 = 8670558
7 + 8670551 = 8670558
59 + 8670499 = 8670558
67 + 8670491 = 8670558
107 + 8670451 = 8670558
151 + 8670407 = 8670558
227 + 8670331 = 8670558
257 + 8670301 = 8670558

Showing the first eight; more decompositions exist.
