Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644764, here are decompositions:

13 + 8644751 = 8644764
41 + 8644723 = 8644764
61 + 8644703 = 8644764
103 + 8644661 = 8644764
113 + 8644651 = 8644764
131 + 8644633 = 8644764
157 + 8644607 = 8644764
211 + 8644553 = 8644764

Showing the first eight; more decompositions exist.
