Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623958, here are decompositions:

19 + 8623939 = 8623958
61 + 8623897 = 8623958
127 + 8623831 = 8623958
151 + 8623807 = 8623958
157 + 8623801 = 8623958
229 + 8623729 = 8623958
241 + 8623717 = 8623958
271 + 8623687 = 8623958

Showing the first eight; more decompositions exist.
