Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628366, here are decompositions:

7 + 8628359 = 8628366
13 + 8628353 = 8628366
17 + 8628349 = 8628366
73 + 8628293 = 8628366
163 + 8628203 = 8628366
179 + 8628187 = 8628366
193 + 8628173 = 8628366
269 + 8628097 = 8628366

Showing the first eight; more decompositions exist.
