Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666224, here are decompositions:

5 + 8666219 = 8666224
23 + 8666201 = 8666224
41 + 8666183 = 8666224
71 + 8666153 = 8666224
131 + 8666093 = 8666224
167 + 8666057 = 8666224
173 + 8666051 = 8666224
197 + 8666027 = 8666224

Showing the first eight; more decompositions exist.
