Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623216, here are decompositions:

3 + 8623213 = 8623216
23 + 8623193 = 8623216
113 + 8623103 = 8623216
149 + 8623067 = 8623216
179 + 8623037 = 8623216
197 + 8623019 = 8623216
233 + 8622983 = 8623216
257 + 8622959 = 8623216

Showing the first eight; more decompositions exist.
