Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643214, here are decompositions:

3 + 8643211 = 8643214
5 + 8643209 = 8643214
17 + 8643197 = 8643214
71 + 8643143 = 8643214
131 + 8643083 = 8643214
137 + 8643077 = 8643214
191 + 8643023 = 8643214
263 + 8642951 = 8643214

Showing the first eight; more decompositions exist.
