Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638896, here are decompositions:

5 + 8638891 = 8638896
29 + 8638867 = 8638896
43 + 8638853 = 8638896
47 + 8638849 = 8638896
53 + 8638843 = 8638896
89 + 8638807 = 8638896
163 + 8638733 = 8638896
199 + 8638697 = 8638896

Showing the first eight; more decompositions exist.
