Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640932, here are decompositions:

43 + 8640889 = 8640932
61 + 8640871 = 8640932
73 + 8640859 = 8640932
109 + 8640823 = 8640932
151 + 8640781 = 8640932
193 + 8640739 = 8640932
199 + 8640733 = 8640932
229 + 8640703 = 8640932

Showing the first eight; more decompositions exist.
