Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639120, here are decompositions:

13 + 8639107 = 8639120
31 + 8639089 = 8639120
109 + 8639011 = 8639120
211 + 8638909 = 8639120
229 + 8638891 = 8639120
271 + 8638849 = 8639120
277 + 8638843 = 8639120
313 + 8638807 = 8639120

Showing the first eight; more decompositions exist.
