Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639306, here are decompositions:

7 + 8639299 = 8639306
43 + 8639263 = 8639306
79 + 8639227 = 8639306
157 + 8639149 = 8639306
163 + 8639143 = 8639306
199 + 8639107 = 8639306
307 + 8638999 = 8639306
373 + 8638933 = 8639306

Showing the first eight; more decompositions exist.
