Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644620, here are decompositions:

11 + 8644609 = 8644620
13 + 8644607 = 8644620
67 + 8644553 = 8644620
109 + 8644511 = 8644620
113 + 8644507 = 8644620
163 + 8644457 = 8644620
167 + 8644453 = 8644620
181 + 8644439 = 8644620

Showing the first eight; more decompositions exist.
