Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8733228, here are decompositions:

67 + 8733161 = 8733228
71 + 8733157 = 8733228
79 + 8733149 = 8733228
109 + 8733119 = 8733228
181 + 8733047 = 8733228
211 + 8733017 = 8733228
227 + 8733001 = 8733228
271 + 8732957 = 8733228

Showing the first eight; more decompositions exist.
