Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709672, here are decompositions:

19 + 8709653 = 8709672
61 + 8709611 = 8709672
109 + 8709563 = 8709672
163 + 8709509 = 8709672
211 + 8709461 = 8709672
229 + 8709443 = 8709672
241 + 8709431 = 8709672
311 + 8709361 = 8709672

Showing the first eight; more decompositions exist.
