Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623746, here are decompositions:

17 + 8623729 = 8623746
29 + 8623717 = 8623746
59 + 8623687 = 8623746
67 + 8623679 = 8623746
107 + 8623639 = 8623746
127 + 8623619 = 8623746
163 + 8623583 = 8623746
167 + 8623579 = 8623746

Showing the first eight; more decompositions exist.
