Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644788, here are decompositions:

7 + 8644781 = 8644788
17 + 8644771 = 8644788
37 + 8644751 = 8644788
59 + 8644729 = 8644788
109 + 8644679 = 8644788
127 + 8644661 = 8644788
137 + 8644651 = 8644788
179 + 8644609 = 8644788

Showing the first eight; more decompositions exist.
