Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639022, here are decompositions:

11 + 8639011 = 8639022
23 + 8638999 = 8639022
31 + 8638991 = 8639022
71 + 8638951 = 8639022
89 + 8638933 = 8639022
113 + 8638909 = 8639022
131 + 8638891 = 8639022
173 + 8638849 = 8639022

Showing the first eight; more decompositions exist.
