Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623782, here are decompositions:

19 + 8623763 = 8623782
31 + 8623751 = 8623782
53 + 8623729 = 8623782
61 + 8623721 = 8623782
103 + 8623679 = 8623782
131 + 8623651 = 8623782
163 + 8623619 = 8623782
179 + 8623603 = 8623782

Showing the first eight; more decompositions exist.
