Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643852, here are decompositions:

13 + 8643839 = 8643852
31 + 8643821 = 8643852
73 + 8643779 = 8643852
103 + 8643749 = 8643852
131 + 8643721 = 8643852
179 + 8643673 = 8643852
181 + 8643671 = 8643852
233 + 8643619 = 8643852

Showing the first eight; more decompositions exist.
