Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655222, here are decompositions:

5 + 8655217 = 8655222
11 + 8655211 = 8655222
73 + 8655149 = 8655222
151 + 8655071 = 8655222
181 + 8655041 = 8655222
193 + 8655029 = 8655222
211 + 8655011 = 8655222
241 + 8654981 = 8655222

Showing the first eight; more decompositions exist.
