Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643284, here are decompositions:

3 + 8643281 = 8643284
61 + 8643223 = 8643284
73 + 8643211 = 8643284
103 + 8643181 = 8643284
151 + 8643133 = 8643284
163 + 8643121 = 8643284
193 + 8643091 = 8643284
271 + 8643013 = 8643284

Showing the first eight; more decompositions exist.
