Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607140, here are decompositions:

37 + 8607103 = 8607140
67 + 8607073 = 8607140
79 + 8607061 = 8607140
97 + 8607043 = 8607140
181 + 8606959 = 8607140
211 + 8606929 = 8607140
229 + 8606911 = 8607140
271 + 8606869 = 8607140

Showing the first eight; more decompositions exist.
