Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639286, here are decompositions:

13 + 8639273 = 8639286
23 + 8639263 = 8639286
37 + 8639249 = 8639286
59 + 8639227 = 8639286
67 + 8639219 = 8639286
79 + 8639207 = 8639286
109 + 8639177 = 8639286
137 + 8639149 = 8639286

Showing the first eight; more decompositions exist.
