Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626678, here are decompositions:

101 + 8626577 = 8626678
149 + 8626529 = 8626678
191 + 8626487 = 8626678
257 + 8626421 = 8626678
449 + 8626229 = 8626678
509 + 8626169 = 8626678
569 + 8626109 = 8626678
617 + 8626061 = 8626678

Showing the first eight; more decompositions exist.
