Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643226, here are decompositions:

3 + 8643223 = 8643226
17 + 8643209 = 8643226
29 + 8643197 = 8643226
83 + 8643143 = 8643226
89 + 8643137 = 8643226
149 + 8643077 = 8643226
167 + 8643059 = 8643226
173 + 8643053 = 8643226

Showing the first eight; more decompositions exist.
