Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628208, here are decompositions:

5 + 8628203 = 8628208
47 + 8628161 = 8628208
59 + 8628149 = 8628208
101 + 8628107 = 8628208
131 + 8628077 = 8628208
191 + 8628017 = 8628208
269 + 8627939 = 8628208
311 + 8627897 = 8628208

Showing the first eight; more decompositions exist.
