Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643792, here are decompositions:

5 + 8643787 = 8643792
13 + 8643779 = 8643792
43 + 8643749 = 8643792
71 + 8643721 = 8643792
173 + 8643619 = 8643792
229 + 8643563 = 8643792
271 + 8643521 = 8643792
349 + 8643443 = 8643792

Showing the first eight; more decompositions exist.
