Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639526, here are decompositions:

19 + 8639507 = 8639526
67 + 8639459 = 8639526
73 + 8639453 = 8639526
83 + 8639443 = 8639526
113 + 8639413 = 8639526
163 + 8639363 = 8639526
179 + 8639347 = 8639526
227 + 8639299 = 8639526

Showing the first eight; more decompositions exist.
