Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626438, here are decompositions:

17 + 8626421 = 8626438
47 + 8626391 = 8626438
89 + 8626349 = 8626438
137 + 8626301 = 8626438
167 + 8626271 = 8626438
257 + 8626181 = 8626438
269 + 8626169 = 8626438
479 + 8625959 = 8626438

Showing the first eight; more decompositions exist.
