Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643822, here are decompositions:

43 + 8643779 = 8643822
73 + 8643749 = 8643822
101 + 8643721 = 8643822
149 + 8643673 = 8643822
151 + 8643671 = 8643822
191 + 8643631 = 8643822
233 + 8643589 = 8643822
283 + 8643539 = 8643822

Showing the first eight; more decompositions exist.
