Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639226, here are decompositions:

7 + 8639219 = 8639226
19 + 8639207 = 8639226
73 + 8639153 = 8639226
83 + 8639143 = 8639226
103 + 8639123 = 8639226
107 + 8639119 = 8639226
137 + 8639089 = 8639226
163 + 8639063 = 8639226

Showing the first eight; more decompositions exist.
