Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607668, here are decompositions:

31 + 8607637 = 8607668
37 + 8607631 = 8607668
67 + 8607601 = 8607668
241 + 8607427 = 8607668
271 + 8607397 = 8607668
397 + 8607271 = 8607668
607 + 8607061 = 8607668
709 + 8606959 = 8607668

Showing the first eight; more decompositions exist.
