Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626558, here are decompositions:

29 + 8626529 = 8626558
41 + 8626517 = 8626558
71 + 8626487 = 8626558
89 + 8626469 = 8626558
137 + 8626421 = 8626558
167 + 8626391 = 8626558
257 + 8626301 = 8626558
389 + 8626169 = 8626558

Showing the first eight; more decompositions exist.
