Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668558, here are decompositions:

5 + 8668553 = 8668558
11 + 8668547 = 8668558
137 + 8668421 = 8668558
179 + 8668379 = 8668558
191 + 8668367 = 8668558
257 + 8668301 = 8668558
401 + 8668157 = 8668558
491 + 8668067 = 8668558

Showing the first eight; more decompositions exist.
