Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639196, here are decompositions:

19 + 8639177 = 8639196
43 + 8639153 = 8639196
47 + 8639149 = 8639196
53 + 8639143 = 8639196
73 + 8639123 = 8639196
89 + 8639107 = 8639196
107 + 8639089 = 8639196
197 + 8638999 = 8639196

Showing the first eight; more decompositions exist.
