Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623740, here are decompositions:

11 + 8623729 = 8623740
19 + 8623721 = 8623740
23 + 8623717 = 8623740
53 + 8623687 = 8623740
61 + 8623679 = 8623740
79 + 8623661 = 8623740
89 + 8623651 = 8623740
101 + 8623639 = 8623740

Showing the first eight; more decompositions exist.
