Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647932, here are decompositions:

5 + 8647927 = 8647932
19 + 8647913 = 8647932
43 + 8647889 = 8647932
53 + 8647879 = 8647932
109 + 8647823 = 8647932
113 + 8647819 = 8647932
131 + 8647801 = 8647932
149 + 8647783 = 8647932

Showing the first eight; more decompositions exist.
