Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639132, here are decompositions:

13 + 8639119 = 8639132
43 + 8639089 = 8639132
181 + 8638951 = 8639132
199 + 8638933 = 8639132
223 + 8638909 = 8639132
241 + 8638891 = 8639132
283 + 8638849 = 8639132
499 + 8638633 = 8639132

Showing the first eight; more decompositions exist.
