Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639606, here are decompositions:

7 + 8639599 = 8639606
43 + 8639563 = 8639606
67 + 8639539 = 8639606
163 + 8639443 = 8639606
193 + 8639413 = 8639606
307 + 8639299 = 8639606
379 + 8639227 = 8639606
457 + 8639149 = 8639606

Showing the first eight; more decompositions exist.
