Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643132, here are decompositions:

11 + 8643121 = 8643132
23 + 8643109 = 8643132
41 + 8643091 = 8643132
73 + 8643059 = 8643132
79 + 8643053 = 8643132
109 + 8643023 = 8643132
181 + 8642951 = 8643132
193 + 8642939 = 8643132

Showing the first eight; more decompositions exist.
