Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623764, here are decompositions:

7 + 8623757 = 8623764
13 + 8623751 = 8623764
43 + 8623721 = 8623764
47 + 8623717 = 8623764
103 + 8623661 = 8623764
113 + 8623651 = 8623764
181 + 8623583 = 8623764
241 + 8623523 = 8623764

Showing the first eight; more decompositions exist.
