Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644822, here are decompositions:

23 + 8644799 = 8644822
41 + 8644781 = 8644822
71 + 8644751 = 8644822
269 + 8644553 = 8644822
293 + 8644529 = 8644822
311 + 8644511 = 8644822
383 + 8644439 = 8644822
491 + 8644331 = 8644822

Showing the first eight; more decompositions exist.
