Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636666, here are decompositions:

19 + 8636647 = 8636666
67 + 8636599 = 8636666
79 + 8636587 = 8636666
127 + 8636539 = 8636666
193 + 8636473 = 8636666
277 + 8636389 = 8636666
397 + 8636269 = 8636666
499 + 8636167 = 8636666

Showing the first eight; more decompositions exist.
