Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639932, here are decompositions:

11 + 8639921 = 8639932
23 + 8639909 = 8639932
29 + 8639903 = 8639932
83 + 8639849 = 8639932
113 + 8639819 = 8639932
179 + 8639753 = 8639932
269 + 8639663 = 8639932
293 + 8639639 = 8639932

Showing the first eight; more decompositions exist.
