Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639726, here are decompositions:

13 + 8639713 = 8639726
79 + 8639647 = 8639726
127 + 8639599 = 8639726
163 + 8639563 = 8639726
283 + 8639443 = 8639726
313 + 8639413 = 8639726
379 + 8639347 = 8639726
463 + 8639263 = 8639726

Showing the first eight; more decompositions exist.
