Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623412, here are decompositions:

3 + 8623409 = 8623412
19 + 8623393 = 8623412
73 + 8623339 = 8623412
151 + 8623261 = 8623412
163 + 8623249 = 8623412
199 + 8623213 = 8623412
271 + 8623141 = 8623412
331 + 8623081 = 8623412

Showing the first eight; more decompositions exist.
