Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623520, here are decompositions:

97 + 8623423 = 8623520
127 + 8623393 = 8623520
163 + 8623357 = 8623520
181 + 8623339 = 8623520
229 + 8623291 = 8623520
271 + 8623249 = 8623520
307 + 8623213 = 8623520
379 + 8623141 = 8623520

Showing the first eight; more decompositions exist.
