Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644998, here are decompositions:

7 + 8644991 = 8644998
41 + 8644957 = 8644998
71 + 8644927 = 8644998
79 + 8644919 = 8644998
137 + 8644861 = 8644998
199 + 8644799 = 8644998
227 + 8644771 = 8644998
269 + 8644729 = 8644998

Showing the first eight; more decompositions exist.
