Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623280, here are decompositions:

19 + 8623261 = 8623280
31 + 8623249 = 8623280
67 + 8623213 = 8623280
139 + 8623141 = 8623280
157 + 8623123 = 8623280
199 + 8623081 = 8623280
229 + 8623051 = 8623280
241 + 8623039 = 8623280

Showing the first eight; more decompositions exist.
