Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626408, here are decompositions:

17 + 8626391 = 8626408
59 + 8626349 = 8626408
107 + 8626301 = 8626408
137 + 8626271 = 8626408
179 + 8626229 = 8626408
227 + 8626181 = 8626408
239 + 8626169 = 8626408
269 + 8626139 = 8626408

Showing the first eight; more decompositions exist.
