Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643432, here are decompositions:

23 + 8643409 = 8643432
73 + 8643359 = 8643432
89 + 8643343 = 8643432
151 + 8643281 = 8643432
223 + 8643209 = 8643432
233 + 8643199 = 8643432
251 + 8643181 = 8643432
283 + 8643149 = 8643432

Showing the first eight; more decompositions exist.
