Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623550, here are decompositions:

3 + 8623547 = 8623550
31 + 8623519 = 8623550
127 + 8623423 = 8623550
157 + 8623393 = 8623550
193 + 8623357 = 8623550
211 + 8623339 = 8623550
337 + 8623213 = 8623550
409 + 8623141 = 8623550

Showing the first eight; more decompositions exist.
