Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626404, here are decompositions:

13 + 8626391 = 8626404
103 + 8626301 = 8626404
107 + 8626297 = 8626404
167 + 8626237 = 8626404
223 + 8626181 = 8626404
263 + 8626141 = 8626404
337 + 8626067 = 8626404
421 + 8625983 = 8626404

Showing the first eight; more decompositions exist.
