Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623404, here are decompositions:

11 + 8623393 = 8623404
47 + 8623357 = 8623404
113 + 8623291 = 8623404
151 + 8623253 = 8623404
157 + 8623247 = 8623404
191 + 8623213 = 8623404
211 + 8623193 = 8623404
263 + 8623141 = 8623404

Showing the first eight; more decompositions exist.
