Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728932, here are decompositions:

5 + 8728927 = 8728932
11 + 8728921 = 8728932
29 + 8728903 = 8728932
31 + 8728901 = 8728932
83 + 8728849 = 8728932
109 + 8728823 = 8728932
211 + 8728721 = 8728932
241 + 8728691 = 8728932

Showing the first eight; more decompositions exist.
