Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644836, here are decompositions:

37 + 8644799 = 8644836
107 + 8644729 = 8644836
113 + 8644723 = 8644836
157 + 8644679 = 8644836
227 + 8644609 = 8644836
229 + 8644607 = 8644836
283 + 8644553 = 8644836
307 + 8644529 = 8644836

Showing the first eight; more decompositions exist.
