Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607666, here are decompositions:

7 + 8607659 = 8607666
13 + 8607653 = 8607666
29 + 8607637 = 8607666
37 + 8607629 = 8607666
79 + 8607587 = 8607666
83 + 8607583 = 8607666
103 + 8607563 = 8607666
127 + 8607539 = 8607666

Showing the first eight; more decompositions exist.
