Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623928, here are decompositions:

31 + 8623897 = 8623928
97 + 8623831 = 8623928
127 + 8623801 = 8623928
199 + 8623729 = 8623928
211 + 8623717 = 8623928
241 + 8623687 = 8623928
277 + 8623651 = 8623928
307 + 8623621 = 8623928

Showing the first eight; more decompositions exist.
