Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643222, here are decompositions:

11 + 8643211 = 8643222
13 + 8643209 = 8643222
23 + 8643199 = 8643222
41 + 8643181 = 8643222
73 + 8643149 = 8643222
79 + 8643143 = 8643222
89 + 8643133 = 8643222
101 + 8643121 = 8643222

Showing the first eight; more decompositions exist.
