Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623242, here are decompositions:

29 + 8623213 = 8623242
101 + 8623141 = 8623242
139 + 8623103 = 8623242
181 + 8623061 = 8623242
191 + 8623051 = 8623242
211 + 8623031 = 8623242
223 + 8623019 = 8623242
239 + 8623003 = 8623242

Showing the first eight; more decompositions exist.
