Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639246, here are decompositions:

19 + 8639227 = 8639246
97 + 8639149 = 8639246
103 + 8639143 = 8639246
127 + 8639119 = 8639246
139 + 8639107 = 8639246
157 + 8639089 = 8639246
313 + 8638933 = 8639246
337 + 8638909 = 8639246

Showing the first eight; more decompositions exist.
