Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755228, here are decompositions:

11 + 8755217 = 8755228
107 + 8755121 = 8755228
149 + 8755079 = 8755228
179 + 8755049 = 8755228
197 + 8755031 = 8755228
227 + 8755001 = 8755228
257 + 8754971 = 8755228
269 + 8754959 = 8755228

Showing the first eight; more decompositions exist.
