Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644932, here are decompositions:

5 + 8644927 = 8644932
13 + 8644919 = 8644932
19 + 8644913 = 8644932
29 + 8644903 = 8644932
59 + 8644873 = 8644932
71 + 8644861 = 8644932
89 + 8644843 = 8644932
151 + 8644781 = 8644932

Showing the first eight; more decompositions exist.
