Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628328, here are decompositions:

167 + 8628161 = 8628328
179 + 8628149 = 8628328
197 + 8628131 = 8628328
251 + 8628077 = 8628328
311 + 8628017 = 8628328
389 + 8627939 = 8628328
419 + 8627909 = 8628328
431 + 8627897 = 8628328

Showing the first eight; more decompositions exist.
