Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623386, here are decompositions:

29 + 8623357 = 8623386
47 + 8623339 = 8623386
67 + 8623319 = 8623386
137 + 8623249 = 8623386
139 + 8623247 = 8623386
173 + 8623213 = 8623386
193 + 8623193 = 8623386
263 + 8623123 = 8623386

Showing the first eight; more decompositions exist.
